I love how this is a mini-game engine that can make fun little minigames. And all you need to do is make a .png with the correct colours in the image, and it becomes a functional, playable minigame. That's pretty cool.

Typically I don't revisit game jam entries, but this I will play around with this for a few of days, just to test things out. This is something I personally haven't encountered in a game jam before (even if there are other like it, this is the first one I've seen). Regardless of the gameplay lacking a bit, I give double props to the underlying concept. 

Nice work!
