Katamari Christmassy

A PICO8+Xmas homage to the Katamari series by Namco by Mathieu @p01 Henri and Matt @gasmanic Westcott

The King of All Cosmos was completely naughty. The stars are all gone and you, the 5cm Prince of All Cosmos, must fix this mess.

How to play

Walk forward with ⬆️, steer with ⬅️ and ➡️
Roll things up with your Katamari ball to build the biggest clump.

The King will make a star with it. If it is big enough.

Game modes

Switch between Story and Arcade mode in the Pause menu.

Rebuild the Christmas constellation in Story mode to make the King of All Cosmos proud.

Have fun in Arcade mode.

Accessibility and photo sensitivity

Some colors flicker at 60fps to make parts of the UI transparent or brighter. Unfortunately this can be quite disturbing for photo sensitive people.

The color flicker can be toggled in the Pause menu.


Code + Visuals: Mathieu @p01 Henri
Musics: Matt @gasmanic Westcott

This is the standalone version of


The tiny racing game in 425 tokens for #17in1jam by @p01 and @Gruber

For the purpose of the jam trying to fit 17 games in one cart, the game had very tight constraint.
The whole game takes 425 tokens, 16 sprites, 16 map cells, 4 sfx and 4 music patterns.


  • 3 in game sfx for the engine noises and transition between tracks.
  • 4 music patterns mixing 3 unique sfx
  • 5 tracks
  • Ghost of your previous laps
  • A nice trophy at the end and a sweet Easter egg

Hope you like it, and will soon try the whole #17in1jam cart!
Curious to read any feedback, good, and especially bad.

It was really fun to make my first game on PICO8

I am still very new to PICO-8 and saw a few games rendered with polygons.
This lead me to the Trifill Thunderdome benchmark by Musurca.

One thing this benchmark didn't show was the number of tokens for each method which is an important detail considering the limitations of the platform.

Also, I wrote two triangle rasterizers in 163 and 335 tokens respectively which perform pretty decently. They might be an acceptable alternative to ElectricGryphon's super fast triangle rasterizer if you need an extra 2-400 tokens. If you don't, by all mean use his. It is the fastest one I found, and by a good margin!

Update 20180706: Added the possibility to switch rasterizer and turn the test triangle with the arrow keys. This allows to compare rasterizers at a normal pace. Updated EG's rasterizer to the latest he posted in the previous thread and added the one from Gryphon 3D Engine Library v2 only modified to use normal color() and fillp().

Update 20180708: Added a fill pattern and a toggle for the results and control wireframe.

Hope this helps,

Hi there. I made a few tweetcarts recently and thought a PICO♪HERO in 280 bytes would be sweet, so here it is.

As you can hear, it's the first time I play with sfx :\

The game features 60 uniques "tunes".
Press the arrows keys to the beat until the end of your tune.

You can see your score at the top of the screen.
Followed by the title of the game and the number of the tune,
Then the music pattern.

Hope you like it,
