Hi, I played the game. I like the simple style of it. The direction switching mechanic looks easy, but is fairly challenging, I also like the music shelf idea and the UI, in general is pretty responsive and fun to play around with, just needs a bit more polish, the edges are pixelated a bit. The simple arcade style is pretty cool but it's just a bit too plain and boring for me. So I suggest, next time spend a bit more time on the graphics too. The gameplay is cool but more variety would be nice, like bigger or faster balls. Besides that this game is a pretty fun creation but could be better. Good job anyways.
