I had a lot of fun on the colorblind-puzzle mode, the others felt frustrating? (I'm very tired after the jam, this might have affected my perception of the other modes). I like the idea, but it seems really hard to find the right balance where it's still chaotic and you feel losing control, but is still engaging instead of frustrating. I might try it again tomorrow... I found myself getting into a fun rhythm, it feels like a game one could play for hours- In any case, the execution is really good, great job!
A minor thing; this is more of a problem to do with itch.io's interface, but on the web version the "check the GMTK's" label gets in the way of the rightmost blocks if I want to see the whole screen.
