I'm working on a game using procedural generation and although the game is nowhere near done I thought the generation technique itself was interesting enough on its own to post about.
Rather than try to explain it myself I'll just send you to someone who already has, better than I likely could. BorisTheBrave: Graph Rewriting for Procedural Level Generation
Instead, I'll just share some of my initial results. The general idea is to generate the "big picture" details first and then successively refine them to build a fleshed out so the levels generated here are shown at 1/8 scale. Eventually every pixel in these maps will expand to be one tile at full scale with additional generation filling in the fine details along the way.

Hey so I was just doing some map work and I was using the cmd+x to move tiles around and I think when I was cutting and pasting somewhere else in the mapview tiles in the shared space it would move the sprites but not the map tiles which was . . . not good and took a while to make sure everything was ok.
It feels like this isn't intentional but I'm not 100%? I'm on 0.2.5c, thanks in advance!
(Like I said maybe this is on purpose since I'm moving the data it's self around in the shared space but in my game I was making I'm using the shared space for sprites and map and it makes it more difficult.)

Credit to blakery, the guy that made C_E_L_E_S_T_E, (a mod of celeste but slower)
I made some changes.
just call this thing "elest"

Controls
- ⬆️ Walk
- ⬅️➡️ Turn left/right
- ⬇️ Toggle basic HUD
- ❎ [X] Hold for full HUD and ⬅️⬆️➡️⬇️ to inspect the surroundings
- ⓩ [Z] Open Inventory/Actions menu
How to play
You initially can't do much -except gathering fruits- more items and actions will be unlocked as you progress in the game.
So just explore the islands and:
- talk to the stone statue/head
- walk under palm-trees to gather a couple fruits if any
Here be Dragons
The writing "Here be Dragons" at the edge of the map means you can't walk farther at that moment:
the game map is initially just a small portion of the full map, next areas will be unlocked by defeating the enemy creatures, just report your success to the statue (Kahuna).

A few days back @dw817 posted a thread about the number of possible combinations in 256 bytes in which they asked:
> Is there a way to calculate 256^256 ?
And knowing there are all sorts of tools and languages which can handle such huge numbers I cheekily posted the answer and caused a bit of a derail.
Anyway, I had some time on my hands so I figured I'd implement large number support for Pico-8.
Edit: Fixed a bug in divide()
Is this likely to be of use to anybody? Probably not. Is it major overkill? You betcha! Though in fairness, at 706 tokens it came out smaller than I was expecting.
Features/Functions
-
bignum(n): Create a 'bignum' with valuenwhich is just a regular Pico-8 number. Most operations require both numbers to be bignums. Sobignum(16000)*bignum(1254)but notbignum(16000)*1254.bignum()is equivalent tobignum(0) -
divide(bn): You can use the division and mod operators (/, %) on bignums if you only need one or the other. Thedividefunction returns both the quotient and remainder at once.q, r = divide(bignum(3)^16, bignum(2)^15) show(bn): Converts a bignum into its decimal representation as a string.factorial(n): Calculates the factorial ofnand returns the result as a bignum. Factorials get very big, very fast so the input tofactorialis just a regular number.+ - / % ^: Arithmetic operators behave how you would expect. All require both arguments to be bignums with the exception of^where only the first argument is a bignum and the second is a regular number. Division is integer division only sobignum(3)/bignum(4)==bignum(0).> >= <= < ==: Comparisons similarly require both arguments to be bignums.
Issues
- The arithmetic operators are all fairly efficent but probably not optimally so.
- I wasn't taking negative numbers into account at all so I make no promises about what will happen if you try to use them. Maybe it will work! (It probably won't work.)
showis extremely inefficient. I'm sure there are better ways to convert very long binary strings to decimal but I'm not familiar with them so this is what I've got. Large numbers (like 52!) may take a bit of time and very large numbers will crash the program as it runs out of memory. (bignum(256)^256 does this, sadly. It calculates the number fine but crashes when you try to convert it.)

A quick and dirty Sudoku solver, may or may not work.
Not sure if there any use-case for such a tool on PICO-8, but here it is.
⚠️ Looking a the source code may or may not induce permanent blindness ⚠️
Controls :
⬆️⬇️⬅️➡️ : move the cursor.
❎ : select a cell/value.
[1️-9️] : fill cell with the corresponding digit if possible.
Pause : access menu.
changelog
2022-11-06:
- added a solve cell option.

Hello.
I use RND() quite a bit, don't you ?
I have noticed in other game programming languages that you can have a 2nd argument for the rnd() command. Currently Pico-8 does not do this. It's quite useful though. Here's an example:
a=rnd(1,10) |
Will for instance choose an integer random number between and including 1 through 10. This:
a=rnd(10,1) |
Will give the same results. This however:
a=rnd(-4,4) |
Will give you a random integer number between and including -4 to 4.
The function of which:
function rndrange(a,b) if (a>b) a,b=b,a return a+rnd(b-a+1)\1 end |
How about it guys and @zep, do you think this is a good addition for Pico-8, to add a 2nd argument to already existing rnd() function ? Or a new function altogether, rrnd() for Range Random.

Project Unicorn, is a small game where you have to exit the city, and go back to the magic garden and find your mom.
you can press x to fight enemies.
it's our first game, and we're very happy to share it with you !
