Really nice game! The art looks pretty and music goes well with it. The idea is also cool and levels built around it do a good job increrasing difficulty.
I did find movement a bid weird since pressing down is actually kind of going right (that might be just me lol) and sometimes the game is a bit buggy, but overall really good entry.
Maybe letting the player hold a key instead of pressing it for every block would be a nice touch. Still, very good game and I enjoyed it a lot. Keep it up!
Would highly appreciate if you could check out my game and leave a rating :)
