Hey there! I just finished a youtube video explaining our donut chess in detail: https://youtu.be/iRcfHCPFgkM

So I thought it'd be cool to show it off here too- it can be played around with at mchess.io/donut - you can also set up an AI or online game on the site.

This is all indie dev work from a couple friends and myself.

It's fun to sit down and draw what the board looks like when you cut and flatten the torus before you watch the video!

Bonus points if you hit upon the other 2D projection that is useful (I didn't)
