Hi! I like the concept of the game, and I think that with a bit more polish, it could be pretty fun!
My main concern is that the player character is a bit too big in comparison to the level, and can get stuck easily on the walls. I think that, as well as resizing the player to be smaller, a touching sprite block instead of a touching color block would make it easier to keep from being stuck inside the walls. I'm also not sure what the variables in the top left is about, and one of them is completely hidden under the other, so if you renamed "my variable" to whatever it corresponds to, and moved the other one out from under it, it'd be more clear what they're supposed to be.
Not bad overall!
