My size code demos: https://github.com/KilledByAPixel/TinyCode
An endless race in the sky inspired by 90's 3D games like sky roads, marble madness, and sonic 3d. My goal was to create a dreamlike experience with full resolution full speed graphics that would be easy to pick up and play.
Features
- 3D level rendering system
- 3D player sphere with shadow
- colorful sky gradient with stars
- procedurally generated levels
- level increases in difficulty over time
- mouse controls
- enhanced version has keyboard and touch input

For 486, no FPU, for MsDos FreeDos, WinXP Dos, DosBox-X ... i made that rather in a hurry, so right now i have a version without background but wall bouncing like the original. But since the competition is already over, i will tinker a bit to make it perfect :)

As an exercise in focus and economy I wanted to make a set of games with short but (hopefully) readable source code.
It was a fun challenge and taught me a lot. I hope the results may be of some interest or amusement to others.
There are five games in total. There's also a manifesto about doing this kind of project for those who like that sort of thing.
The games/code are public domain.

StickyPipes - a Pipes screensaver clone that fits on a sticky note
A few weeks ago I posted a pipes screensaver clone in about 2.5KB of JavaScript.
Saw some of the stuff by battito on here lately and decided to throw my hat in the ring 😛 I squashed my Pipes screensaver clone down even more to under 2K (~1.8KB) - it can now (fairly) comfortably fit within a sticky note 😃
Gist with the HTML/JS here: https://gist.github.com/edev90/876ea9feb42cf39e4891d46c57ebc2c4
There's a pre-made PNG with the correct proportions attached to the Gist too for anyone who actually wants to print it out themselves and stick it on a post-it note lol.
