I played your game with a group of friend at my house and we really enjoyed it.

The core idea is really fun and deep, even tho it's incredibly simple.

The only criticism I can give is that sometimes the colours can be a little confusing. In particular, I found that the blue and purple characters were often mixed up during gameplay. I would suggest using more distinct colurs in the future, especially when using small object like the disks.

Other than that, great game!
