I'm creating an image using this
texture = userdata("i64", 3, texture_width * texture_height )
and setting it up like this
p.texture:set(0,i,flr(xx),flr(yy),flr(1+(color_offset+(noise_value+1)*5)%30))
which I can draw with
pset(p.texture)
and is properly drawn (it's the rectangular image)
But I don't need floats! I wanted to define it with i32 instead, like this
texture = userdata("i32", 3, texture_width * texture_height)
But then it's not drawn at all:
Doesn't pset work with i32 userdata? Or should it and I'm doing something wrong? The only thing that changes here is how I define texture with f64 or i32...

Here is my first game, a hiking simulator.
I love hiking and outdoorsy stuff in general.
There is no goal here, just go for a hike and enjoy the peaceful scenery.
The controls couldn't be simpler. Just press right to hike or release right to enjoy the majesty. You can't go back the way you came.
This was fun as it was an exercise in rendering a full background without making a map at all.

NOTE: New update to version 1.02! Read the change log for more info!
Hey you! Have you ever wanted to make your own Celeste levels, but have no idea how to use Pico8 what-so-ever? Well now you can with Celeste Maker, a simple level-pack editor to design your very own level-pack and save it with others!
How do I use the editor?
The editor interface is decently simple.
Use the arrows to move the player (and camera).
To draw terrain and place objects, simply click on an element in the topbar, and start drawing.
The tiles will (usually) automatically connect themselves. You can erase tiles by clicking on the eraser on the sidebar

WELCOME TO DASHBOX
DASHBOX is a frenetic arcade score chase game where you DASH inside a BOX.
Get to the SAFE WALL before the timer runs out.
Collect the ORBS to increase your score.
Avoid crashing into the GATES!
HOW TO PLAY
In DASHBOX you control the ball that sits on the interior edge of the wall.
Use left, right, up, and down to move your ball along the wall.
To DASH, hit the Z key (or circle button)
If your path passes through a GATE, your trajectory will be changed!
The WHITE WALL is the SAFE WALL
You want to make sure you're on the safe wall when the timer at the bottom of the screen runs out
To increase your score, collect the vibrating ORB.
The point value of an orb increases by 1 for every orb collected while the timer is active, so move fast to get quick points!
IF YOU DASH TOO MANY TIMES WITHOUT COLLECTING THE ORB, YOU WILL PERISH.
WAYS TO DIE (AKA THINGS TO AVOID)
- Being on a non-safe wall when the timer expires
- Colliding with a gate in a way that does not redirect your trajectory
- Dashing too many times without collecting an orb
Have fun, and chase the highest score!
This game is a Zeflyn Design
a portion of the development for this game was streamed live on my Twitch Channel:

What happens in the cart above
The program iterates over an array of tables moving values from the previous table to the current one tt[i] = pp[i] and displays current memory consumption and cycle counter
Expected behavior
Memory consumption does not grow given the fact that no new objects are created and the previous table is cleared by setting pp[i] to nil;
Actual behavior
Memory consumption grows and eventually crashes the program.
Doing a manual table reset t[counter - 1] = {} solves the issue, but in an actual game this manual GC call is very expensive(Example)

This a simple program to test the buttons from your keyboard and gamepad. I built it as a reference, so I can know where each button (especially the action buttons) is on the gamepad. The other programs I tested weren't aligned to my xbox styled gamepad.
Since it's a windowed program, it can be installed as a widget.

So I have this planet generator that creates a texture and a set of points as userdata, drawing the planet with a single pset(planet.points) line. But then I want to animate it so it looks like rotating. In each frame I get the UVs for each point, sample the texture with an offset and I get what you see in that image, but rotating. Looks nice.
So far so good except because it's painfully slow - a planet with radius 32 is drawn at 15fps :(
So I thought I could speed this up by precomputing UVs and got to something like this to update the animation:
for i=1,planet.discArea do
local tx,ty = planet.uvs:get(0,i,2)
local xx,yy = planet.points:get(0,i,2)
tx = (tx + planet.rotation) % texture_width
local index = flr(ty) * texture_width + flr(tx)
local a,b,c = planet.texture:get(0,index,3)
planet.points:set(0,i,xx,yy,c)
end
Which got me exactly to the same outcome, at exactly the same fps :'(

I was recently pretty interested in fractals and had seen a few videos about them so i decided to try and make a mandelbrot fractal renderer, which in my opinion works pretty well
Explore the fractal with the arrow keys and zoom in with X and O
+ if you were interested in any other fractals than the Mandelbrot set, here is the burning ship fractal:

First finished Pico8 experiment. This is a kind of white noise machine in the form of a mini aquarium you can change some settings for. You can tap on the glass to find some interactions with the creatures and influence their behaviors. I made it as an idle app to run on my retro handhelds while they sit on my desk. Enjoy!
Arrow keys/Directional pad = move the cursor
x key/button = click on buttons or tap on the tank to trigger "ripples"

Hi there! I want to purchase Picotron before the discount ends, but I'm not able to buy it for some reason.
After entering the card details, it simply leads to an error page, and my card isn't charged.
I'm using a gift card, and was wondering if that could be the problem?

Made a simple reactive wallpaper and screensaver. Might be bit simple but it looks quite nice and is quite satisfying to watch.
Feel free to modify/fix anything on the carts. Tips and tricks are welcomed.
Screensaver changes pattern every 20 seconds

This is a post of my fishing game!
Instructions
Press and hold 🅾️ to prepare to cast, and let go to launch your lure!
Then, tap or hold 🅾️ to retrieve your lure. Float your lure in front of a fish to get its attention. It may take some time to get it interested. Once you've got it interested for long enough, it will strike! Now, hold 🅾️ to reel in that fish. The line color indicates tension. If the line is under too much tension, it will break, and you will lose a lure. Keep your tension balanced, and the fish will eventually tire out and become easier to fight.
Catch all the fish in the pond to win!
You will lose if you run out of lures or if you run out of time.

This is a cart to view png or qoi images in Picotron. It uses @pancelor's import png library. It's basically a different frontend for import png.
You can zoom in/out an image with scroll wheel, and pan across the image by dragging.
You can copy the image as a sprite to clipboard by pressing Ctrl+C.
You can open png and qoi images (as well as pal and hex pallets) by dropping them on the window (or, default_app png /path/to/imgviewer.p64 to set image viewer as the default app for pngs).
The statusbar shows the size, viewport position (coordinate of top left pixel), zoom, and loading progress.
The image used in the label preview is

Hello, this is my first attempt at a pico 8 game. I can't code very well, so I had some assistance from Claude AI :)
It's a simple Shoot'em Up game that gets more difficult as you progress.
How long can you survive?
Post your high score!
Update:
- added enemy fire (starts at lvl 5)
- menus/title screen
- level progress improvement
- updated sprites
- other small things, and bug fixes

Press X to jump.
This is a platformer experiment based on Advanced Micro Platformer by @mhughson. Art by Niall Chandler Games.
Landing on top of blocks generally works well, but bumping into the sides of them is glitchy. Especially for the faster dirt blocks in the foreground. This is because of the hacky way I'm doing collision detection across the different layers.
