A minimalist reaction game inspired by racing games and playing with a stopwatch.

V1.1 - Squeezed in ending message, improved enemy collision
Join Pico-8 Mascot Jelpi on a run and jump adventure. When out for a paddle in his canoe one day, Jelpi got swept over a waterfall and ended up in a strange land filled with creatures who don't seem very friendly. Travel though grasslands, forests, and cliffs on your way back home, hopefully in time for dinner.
Controls:
Dpad - Run
Z/C - Jump (hold to boost off enemies)
This game was created for Pico-1K jam 2025, and has been squished down to within an inch of its life to fit a multi-stage platformer in just 1024 compressed bytes.
Galactic year 2387. Things have been rather dull on your first assignment for the Star Corps, patrolling a quiet trade route. Suddenly a massive, deadly Zorlon swarm appears, seemingly from nowhere, and you're the only thing standing between it and a nearby peaceful planet. You frantically punch out a distress call, but a sinking feeling in your gut tells you help might not come soon enough. Well, time to blast as many as you can...

This is my attempt at fitting a simple shmup into <=500 characters for Tweet Tweet Jam 10. Shoutout to Krystman, whose Youtube shmup tutorials were a big inspiration.

- Version 1.04
This is a complete recreation of the original Super Mario Bros, crammed into under 24KB of a Pico-8 cartridge (spritesheet memory is unused). The code is all new and not ported from the original game, so things work differently, but I tried to make it feel similar.
It includes all original levels, the minus world, and the second quest. Due to the token limit and limited likelihood of use, the alternating 2-player mode has been replaced with just playing as Mario or Luigi. Hope you enjoy playing!
Controls:
L/R--------------Move/Select world on title screen
X/V--------------Run/Shoot Fireball
Z/C--------------Jump/Start
Changelog:
V1.01

This is a scaled-back version of Celeste Classic in just 1KB of compressed code. Originally planned to submit it to Pico1K Jam 2024, but didn't make the deadline. It includes the first 3 levels of the original game, and runs at 60FPS. I tried to make it feel as much like the original as possible, hope you enjoy playing it.

System Rebooting...

Recalculating mission parameters...
- Explore newly-discovered subterranian biome of exoplanet and reacquire 4 missing mobility components and 8 power cells
- Attempt to resurface and rendezvous with mobile base to transmit stored data and receive necessary repairs
Minimal power remaining...
This is my entry for Pico1K Jam 2024, and my first attempt at a Metroidvania game. Hope you enjoy playing it!
V1.01: Wall jump behavior is now more consistent, and destructible blocks now differ slightly in appearance
V1.02: Fixed double jump glitch
V1.03: World map generation hidden at startup

This is a version of the Snake game that came on old Nokia phones, complete with simulated phone bezel and greenscale display. To fit within the 500 character jam limit, I had to change a couple mechanics to save space, which made it play a bit more like the later Snake II, so I guess you could think of this as a a late 90's missing link. The name's also a reference to an awesomely funky 70's sci-fi show. https://www.imdb.com/title/tt0072564/ Hope you enjoy playing it!

V1.02 --Added Minus World
V1.03 --Fixed minus world bugs, completed scoring system, tweaked jump physics
This is a demo for my Pico-8 port of Super Mario Bros., and it includes all of World 1, along with the secret 'minus world'. I plan to reskin the game before a full release to avoid potential Cease-and-Desist letters, but wanted to give people a taste of it in its original form. Also, not everything is quite finished, and I figured this would be a good way to get some playtesting and feedback, so please let me know if you encounter any bugs.
Special thanks to:
- Jwinslow23 for composing the music and many of the sound effects
- Zep for his PX9 compression system

For the past several months I've been working on a full port of the original Super Mario Bros. for Pico-8. Just today, I was working on implementing level checkpoints, and a few hours after stopping work on the prototype and putting my laptop to sleep, I came back to it. As happens sometimes, Windows went through a lengthy update process, and after it ended I attempted to bring up the file, and this did not work. On investigation, I found that the file now took 102KB, and was unloadable. I then attempted to load it using Notepad++, but all I saw was a tremendously long single line of blank spaces that read "nul" when I highlighted them.
If anyone knows of any methods for recovering .p8 files that have become corrupted, I would greatly appreciate any advice. I have been saving the prototype using the same file name for a long time, and the most recent alternate version I have is from 3 months ago, and it would require a great deal of time and work to rebuild.

I was wondering, what's a good straightforward way to directly record video of your Pico-8 project with audio? I've been working to implement music and sound effects in a game, and wanted to figure out how to share what it sounds like without requiring people to download the unfinished cart. I imagine I'm far from the first person to ask this, but a search didn't turn up any results. Thanks.

v1.1: Fixed occasional impossible jumps
This is a little endless runner game featuring Pico-8 mascot Jelpi in just 500 characters of code. I tried to cram in the best graphics and parallax scrolling that would fit. Hope you enjoy it.

This is a work-in-progress demo of my Pico-8 port of the original NES Mega Man. It's a longer-term project, so I figured I'd put out some demos as I finish parts of it.
V1.0:
- Cut Man's stage playable with enemies, objects, powerups, music, and sound effects
(music and sound effects by @ScrubSandwich)
V0.1:
- All 6 robot master stages available to explore, but no enemies or sound

Just updated to v0.2.5e, and found that it breaks a number of my tweetcarts.
The issue specifically seems to be that this shortcut is no longer supported:
if(...)do --thing1 --thing2 --etc. end |
Now to make things work, I have to replace the "do" with "then". Not a huge change, but it does require a couple more characters, and every one counts when dealing with strict character limits.

I've been working on a platformer game engine for a little while, but I'd only made a basic run-and-jump. This was an excuse to develop something more capable. While I'm not immediately planning to demake an entire Mega Man game, with PicoMap, my metatile-based map system, it seems possible. I've been working on pixel art and layouts for some levels, so I'll see where things go.
Changelog:

I've been working on building a simple and efficient platformer engine, and while it basically works, the character sprite can appear jittery depending on the character and camera movement, and I haven't figured out why. I've uploaded a prototype it you'd like to check it out. If anyone has some ideas or suggestions, I'd appreciate it, thanks.

A segmented LCD-style clock. It's pretty simple, but figuring out an efficient way of storing the graphics and not using any spritesheet space was interesting. Entry for the Pico-8 512-Char Jam.
