It's been two weeks since I've released Super Charrio Kart as an April Fool's joke, and after a lot of deliberation I decided it would be best to make it open-source. So if you just want to make a couple of tracks, make your own game or add multiplayer to it feel free to do so!
The entire project is build with plain old JavaScript, HTML and CSS and uses
Howler.js for easy sound playback and
three.js for cross platform webgl rendering.
