Welcome to the Lumon Family

Congratulations! 🎉
We are all thrilled you've decided to become part of Macrodata Refinement department, here at Lumon Industries.
We shall now begin your orientation on being a successful Macrodata Refiner.


  • Examine the numbers displayed in the data field in front of you which need refining.
  • Using the roller ball, move the magnifying glass around the data field and see the numbers enlarge as it passed over them.
  • Periodically, certain numbers may start to make you feel a certain way.
  • There are four categories of numbers, each of which elicits a different feeling.
    • WO - These numbers elicit melancholy or despair.
    • FC - These numbers elicit joy or ecstasy.
    • DR - These numbers elicit fear, anxiety or apprehension.
    • MA - These numbers elicit rage or a desire to do harm.
  • When you are ready, try highlighting a group of numbers by clicking and dragging over a data set. Then release to automatically drop the numbers into a bin.
  • Once dropped into a bin, a progress report will display, showing the levels of each number type within that bin.
  • Your job is to fill all five bins evenly, with the four kinds of numbers.
  • Should you have any further questions, feel free to ask your supervisor.
    ...and remember - when you reach 75% completion, you'll be rewarded with a
    Music/Dance Experience! 🕺🚥

Happy Refining and Praise Kier! 🔢⤵️🗑️

🌐 https://itch.io/jam/pico-1k-2022

You have until the end of September to make cool things in PICO-8
...by using only 1K (1024) Compressed Bytes of code 🗜️

No pre-defined Sprites, Maps, SFX or Music data allowed.
ALL content must be created using code.

It can be a:
🕹️ Game
🎞️ Demo (Animated or Interactive)

UnDUNE II is a demake of the classic (and original) RTS game DUNE II, re-created from scratch in PICO-8.

A strategy-based resource management simulation, where three houses fight for control of the planet Dune - the land of sand and home of the spice.

This project started as a fun idea, that I expected to get done within a month or two.
Well... almost 3 years later (working on & off, in my free time) - I'm happy to say that it is finally finished! 😅


👥 All 3 Factions (+Sardaukar)
👨‍🏫 All 3 Mentats (+Bene Gesserit)
️🗺️ All 9 Mission Levels (inc. anim map w/ intros)
🔊 Music + SFX remade for PICO-8 (by @Gruber)
🏭 All 19 Building Types
🚛 All 21 Unit Types
🏯 All Palace Weapons
🏨 Capture Buildings (inc. Harvesters)
🐛 Sandworms
️⛰️ Multiple Terrain Types
️️⛏️ Spice Blooms
🌁 Fog of War
📡 Low/High-res Radar
🤖 Multiple AI Opponents
💾 Auto-saving after each Level
📊 Level End Stats (w/ Rankings)
💾 ️Spanning 12 PICO-8 Carts
️🖱️ Mouse/KB/Gamepad/Mobile-Friendly
⏳ HOURS of gameplay!


Mouse (Recommended)

  • Left-Mouse-Mutton: Select Unit/Building, Choose destination/target
  • Right-Mouse-Button: Deselect/Cancel



If you've never played the original (or an old-school RTS) before, the basic principle of UnDUNE II is as follows.
Build up your base by ...building! (just remember to put down concrete slab foundations before placing your buildings, to avoid damage).

Wind Traps generate electricity to power your buildings. Refinery's take raw Spice (mined by Harvesters), which are converted into credits, to allow you to build more! Take your units and explore your new terrain.

But watch out, as you are not alone. There are two other foreign factions that will fight you for control of Dune. Not to mention the native lifeforms - such as Sandworms, which can swallow units whole!

Units can be instructed to attack enemy units and may automatically retreat when outnumbered. Harvesters will automatically try to find the closest spice, but can also be told where to mine - they'll also automatically return to base for unloading when full.

Grow your base, expand your building options as you go (more will unlock at later levels). Preserve your Construction Yard at all costs - you can't build another one!
(unless you have an MCV...)

Good luck! 😀🎖️
...feel free to share any cool pics/vids using #UnDUNE2 hashtag


Pre-built Win, Mac, Linux, RPi executables can be downloaded from the UnDUNE II itch.io page.


  • Improve radar quality by building a Radar Outpost
    (ensure sufficient power levels are maintained to keep operational)
  • Certain buildings require other buildings to be built before they will be available.
  • Other buildings and units will unlock at the later levels.
  • If you need credits fast, you can send a Harvester back to Refinery early.
  • Some units are only available to certain factions -
    such as Harkonnen Devastator, Ordos Deviator, Atreides Sonic Tank.
  • Build a Repair Centre and units will try to go directly to them get fixed without you having to tell them.
  • Build base foundations quickly by placing 4x4 Concrete Slabs (when unlocked)
  • Build a Carryall as soon as you can (via Hi-Tech Factory) -
    as they will pick-up/drop-off units (such as Harvesters and retreating units) MUCH faster.
  • Trikes are fast and inexpensive - use them to scout enemy bases
    (just make sure you're prepared for a fight once they know where you are!)
  • Sandworms cannot "eat" units if they are on land.
  • Spice Blooms (mounds) can be shot to release payloads of spice.
  • Build an MVC and send it into corner of map
    so you have a "backup" Construction Yard, should your only one be destroyed.
  • Target enemy Spice Refinery first, to stop them from earning credits,
    then go for their Repair Facility and then Unit Factories.

Hi @zep,

Unless I'm missing something obvious, I seem to have stumbled on a weird bug.

It seems that inside an FOR..LOOP (potentially other places too),
if the incrementor is something other than 1 or 0.5 (such as 0.4),
then even though PRINT is "saying" the value is 1.4, it is not comparable with that value
(perhaps a precision/rounding happening in PRINT?)

Code below:


?"-- works -----"
for z=0,3,.5 do
    if(z==1.5) print("😐")

?"-- fails -----"
for z=0,3,.4 do
    if(z==1.6) print("😐")  --<<<< NEVER hits this 

Hope this helps (or someone can point out the error of my ways!)

The 💾 PICO-8 Giveaway period has now ENDED.

What WAS it?

I decided I'd like to do a giveaway for FREE copy of PICO-8 💾

...then the following lovely people decided to match my donation! 😲

So we now have 53x Free copies of PICO-8 to giveaway! 🥳

If you would also like to ADD to the Donations (but please, ONLY if doing so will not put you in any financial difficultly), then please feel free to message me directly on Twitter!

Why are you doing this?

PICO-8 has been, without a doubt, one of the best purchasing decisions I've ever made. 😊
It's brought me countless hours of joy, creativity and (in some cases) career opportunities.

From time to time, I see someone that seems very keen to start experimenting with PICO-8, but they simply don't have the budget for the (very reasonable) $14.99 price tag. It makes me wonder what they might've created, if given the option.

Well, I'd like for someone to have that option. 🤓

How do I enter?

To enter - simply reply to this thread, saying (in 50 words, or less)

  • Why you would like to win and, ideally...
  • What you would create with it (should you be lucky)?

What are the terms?

  • Open to everyone, in all countries... NOW!
    • (but PLEASE, do not enter if you already own PICO-8, or can comfortably afford it)
  • Only one submission allowed, per person
    • (don't attempt to abuse this - just be nice to others!)
  • Closing deadline is this Saturday 6th July @ Midnight (GMT)
  • After closing, all qualifying entrants' usernames will be fed into an online random selector
  • I'll then ask the winners to contact me directly with their e-mail addresses, so that I can "gift" them each a copy of PICO-8.
  • The organiser's decision is final.

Any other questions (or anything I've not covered), please let me know.

Hi all,

I'm producing miniature physical releases of Low Mem Sky (my attempt to "demake" No Man's Sky),
as a THANK YOU to my supporters on Patreon. 🙏

I not sure, but I think this is the first time anyone's tried (bothered? 😅) to create a "physical" release for a PICO-8 game.

Hey @zep,

Looks like the ability to load carts via their BBS post ID is currently broken?

Which, with the current absence of the [Copy Cart] BBS feature - means it's a bit of a faff to load a BBS cart into standalone PICO-8.

Thanks in advance.

Low Mem Sky: L A S T

You awake to find yourself on an alien planet, with the desire to achieve one thing... reach the centre of the galaxy!

Made in PICO-8 for #DemakeJam 2018, where the original build came 3rd Place.


  • Around 180,383,121,450 unique star systems... (I think!)
  • Each system with...
    • Up to 8 procedurally-generated planets
    • Space Station for trading resources, components and ship upgrades
      (all at system-varying prices)
  • Each planet with unique...
    • Continuous procedural terrain generation
    • Climate-specific resources and collectables
    • Seven base alien species (land, water and air-based) + Sentinels
  • Five different ship classes - all with different specs (speed, capacity, warp range)
  • Auto-save & Restore of progress
  • ...all within a single PICO-8 cart!

Planned Features: NONE (No more room!)


On Foot:

  • ARROWS = Walk around
  • Z = Run (Hold)
  • X = Collect Item / Take-off (when close enough)
  • ENTER = Quick Menu, with options to
    • "Call Ship" to current location
    • (Also an option to delete save/progress - use with caution!)

Space Flight:

  • LEFT / RIGHT = Rotate
  • UP = <Unmapped>
  • DOWN = Open Galactic Map
  • Z = Engage Pulse Engine boost (Hold)
  • X = Land / Dock (when close to planet / station)

Hi @zep,

Before you pull the trigger on v0.1.12 - can I ask whether you've enabled extcmd in binary exports?

I just assumed it would work as the screenshot/gif record facility is there in exports, but when I try the code below on a Mac binary export (which is still 32-bit BTW), it does nothing:

extcmd("screen")  -- works in PICO-8, not in binary export?

Is this something that could still be rolled into the next version?

Thanks as always! :D

Someone reminded me that I'd never actually posted this silly little line thingy that I made last year while I was bored on a flight. So, enjoy! :D

Santa is relying on you to sort the presents to the correct destination tube.

  • Presents sorted incorrectly will lose points.
  • Dropped presents will lose a life!


  • X = Start Game
  • LEFT/RIGHT = Move Elves
  • UP/DOWN = Hi/Low Bounce
  • Hold X + LEFT/RIGHT = Change Bounce Angle

My entry to the 3-Color Jam (#3CJam), where you had to create a "spooky" game that used no more than 3 colours (and yes, Black is a colour!). It is an attempt to make a short adventure game, based heavily on the movie "Halloween" by John Carpenter.

I created it using my SCUMM-8 point & click adventure game engine (GitHub link)

However, due to the BBS web player not hiding mouse cursor and right-clicks,
I recommend playing it on My itch.io page (LINK)

Also, for the best effect: turn the lights down and the sound up or headphones)! :D


  • Mouse is recommended
  • (Arrows / Z / X - will also work)


  • If never played a "Point+Click" adventure game before...
  • Simply use the cursor and (left) click where you want the player to Walk To.
  • To interact with objects, click on the Verb you wish to perform, then click on the object.
  • For example, to Pick-up the Knife... simply click "PICK-UP" and then click on the "Knife" object in the scene.
  • When hovering the cursor over objects, their default verb/action (if applicable) will be highlighted. In this case, you can simply Right-click on the object for the default verb/action to be performed.


  • Code, Art & Music (cover): Paul Nicholas ( @Liquidream)
  • Additional design by Hilda Nicholas.
  • Original "Halloween" Music, Concept & Credit: John Carpenter


 * [b]FIX[/b]: Issues with wardrobe doors
 * [b]FIX[/b]: Replaying intro when re-entering first room
 * [b]FIX[/b]: Display issue if user clicks after ending
 * [b]CHG[/b]: Now only offers hint once you've looked at a certain object.
 * Initial version

Another World: SURVIVAL
Imagine the game Another World, but with endless waves of enemies to fight! (#LOWREZJAM entry)

This was my entry to the #LOWREZJAM, using a display of only about 1/8th of the Pico-8 display (64x32 pixels), is a new spin on an old classic!


  • Arrows = Move player left/right/crouch
  • Z = Kick
  • X = Fire laser - when you get the gun at Level 3
    • (Hold for a few seconds and release to create a defence shield)
    • (Hold for longer to release a BLAST to destroy enemy shields)


  • Endless number of levels
    • (Theoretically!)
  • Several classes of enemies to survive from:
    • Water tentacles: Don't linger too long next to the pool!
    • Worms: If they sting you, it's game over!
    • Soldiers: They will use all their skills to defeat you!



 * ADD: Music and SFX! (+can be toggled on/off in menu)
 * ADD: Auto-save of progress (+menu option to reset progress)
 * FIX: Player collision hitbox
 * ADD: "Elevator door" (kinda) transition at start of Titles
 * FIX: Double-play of "gun pickup" cutscene
 * Initial version

Here's my PICO-8 tribute to my favourite end-of-game music, "Still Alive" from Portal.
I also replaced the original credits with some shout-outs to the PICO-8 community! ;o)

Hope you like it and don't forget: the cake is a lie!

(P.S. - The original game music was done by Jonathan Coulton)
