Awsome, simple puzzler!! Short, easy to understand (except maybe that the colors youn get are in order, independent of which tile you die at). The last one was actually a bit challenging, and the other ones were great too!
But unfortunately I gotta say that your coveré-art is better than the ingame game graphics. (that's basically all I could think of about what I'd change in the game, so this is very well done!)
PS: if you played my game too, that'd be super duper apreciated! https://theothetorch.itch.io/blue-insides
