Would you enjoy more of this game concept?
yeah I like it. I like the music too, it's just not looping :( . Just to say that I think it would be better to start with ultra simple levels to get the rhythm of the game and hook the player.
Ahh and good also about the art, if it's pixel art that the whole game has the same resolution that would be good. For example, you can see that the pieces are scaled.
Also maybe, thinking (not very well) maybe it would be good to add coins with which you can use in a store, but it's just a crazy idea. You should evaluate that. Good game :)
