Quite some originality here with the disappearing blocks, i also liked the fact that you can take your time to plan things out before going about and having the blocks time out and the quick restart button is quite welcome as well.
I'd say the game is quite well designed overall, the tutorial is pretty clear, although the repeat mechanics are still a bit confusing at first. Solid game anyway, and the pixel art and music are both really good.
Congrats !! :)
