I know a lot of people have posted functions for drawing cubic bezier curves, but I'm tossing my own into the pot because why not. Just skimming threads, it feels like most people use pset() to draw them pixel by pixel; this one uses line() to draw them segment by segment.
Some animated gifs, because they're fun:
To save you digging into the cart, here's the two versions of the algorithm I'd recommend, based on my testing. If you want to see how fast they run, there's a pause menu item in the code that draws sets of 5000 random bezier curves with a bunch of different algorithm parameters in two sizes - 16-pixel square bounding box and 128-pixel square bounding box - and adds up the total CPU needed at 60 FPS.

Something is awry at December Village.. Everyone is unhappy; Record time blues!
It's up to Deci to run around and use her boombox to cheer everyone up!
Talk to villagers and find songs to play, Or just take a nap that's fine too.
Kinda a mess and experimental but hope it's chill. Happy holidays!

Futureleste aims to be a mod set decades after Celeste Classic. All the snow has melted due to global warming, and the ways of dashing have been forgotten. Madeline's descendant has to relearn the ancient techniques, and maybe even surpass her ancestor.

A little holiday puzzle game!
It was kinda rushed in 1.5 weeks to be done before christmas, so it may have some bugs...
I think perhaps I could have developed some ideas and made some more advanced complex puzzles, but that will be for a possible sequel or update.
Hope you enjoy anyway! Happy holidays!

Building a PICO-8 Beatemup part 1
Introduction and Aknowledgements
Hello and thanks for reading. This post will be an explanation of the basics of my Ninja Turtles beatemup engine. I'm going to try and explain every single step along the way so this will be a fairly long post. You should probably have some familiarity with basic development but I'll make this as understandable as possible across skill levels.
This blog post obviously owes a lot to a lot of people but much of this specific workflow was derived from these two posts:
and
Using _𝘦𝘯𝘷 in PICO-8 by slainte.
Please read both if you have not. Neither is a prerequisite, but you'll be glad you did.
Help Wanted
I’m not a programmer by trade so I’m looking forward to learning from the community by explaining what I’ve created to people who are smarter than me, and receiving feedback on improvements. I hope this helps anyone along their own path. Please feel free to use this code or anything you find in any of my stuff, really. I'd love to play your game some day.

SNOWSTORM - A short graphics and sound demo for PICO-8
Here's my entry for Twelve Days of PICO-8 Christmas 2022! I would've liked to have put something a little more substantial together, but I'm happy with it as it is ❤️

Edit: I wrote this question very late at night, and my grammar wasn't that great. I fixed my bug report to be more clear to users what the issue is.
The function "Box" doesn't draw relative to the screen like boxfill does, and box and boxfill don't round the XYZ coordinates the same way.

Changelogs v2.0
- Added difficulty level selector.
- Adjusted velocity of asteroids according to size of asteroids: bigger asteroids will be slower, and smaller will be faster.
- Now all asteroids will always have, relatively, equal sizes at the start of the game.
- Added counter of total destroyed asteroids.
- Added stats of number of destroyed asteroids.
- Randomize color of the ship.
- Added music.
Edit: desactive key binding for reset best time in game over screen as can be easily pressed by mistake in mobiles.

installed windows (in corridor)
prevents attacks from happening twice in a row
gaster blasters spawn cooler

Hello, I am trying to pass my player.score variable (an int from 0 to wherever), using GPIO.
I have been using poke2(location, player.score) and then reading to the browser using pico8-gpio-listener.js library by Ben Wiley.
However, my player.score maxes out at 255 and then resets to 0. This doesn't seem right so any help would be appreciated. The player.score itself goes as high as I need it to, it's just when I use poke2() it limits to 4bits(?) I think.

The other day I pasted together a mockup to see what Picotron could look like on a 4:3 CRT monitor, see photos below.
I noticed the display spec for Picotron says 480x270. @zep, Have you considered allowing other video modes, like 320x240?

Hi! You want to draw pixel art? You like puzzle games? You can't wait for Christmas? Well the game's for you! Solve puzzles by following clues on grids to draw pixel art that'll turn onto Xmas-themed patterns. Each solved pattern is saved and retrieved in following sessions.
Xmas Patterns is part of the Twelve Days of PICO-8 Christmas 2022 you'll find there: https://www.lexaloffle.com/bbs/?tid=50644
The game lacks a proper ending and some other bits I'm probably the only one to know. Despite two months of work the game's never looked like it wanted to be finished. It's sorry about that and hopes you'll like it nonetheless.

Hi Zep! :) I think I found a bug in one of the more esoteric stat calls?
Bug:
According to the manual, stat(56) should return the number of ticks played in the current pattern. Currently (0.2.5e), it seems to poll the leftmost sfx in the pattern for the count. That makes sense bc the overall pattern length is determined by the leftmost sfx which is not a loop, but as the title says, stat(56) will reset back to 0 early if the leftmost sfx is a loop.
Expected behavior:
stat(56) should return the number of pattern ticks played regardless of looped sfx
Thanks for your time! :)
