I love the idea of the game and the puzzles. Three colors give you an unexpectedly big variety of combinations. I have enjoyed combining them and experimenting.
There was a bit of a problem with the level two, though. It’s not very obvious that you need to drag gray blocks and jump on them. Maybe I missed the explanation. Also, It’s easy to get stuck in the beginning because you are experimenting with paint and have only a set number of gray platforms. Quite soon, I found myself running out of both.
The idea again is great, but maybe you need to organize puzzles in a way so there is no option for a player to get stuck. Or if you are stuck, you should understand why and how to fix it. Hope this helps :)
