It was alright.
It wasn't too original, but it didn't lag, it was fun, the graphics were simple but nice, there didn't seem to be any glitches, and so on. I liked how the level increased as your score did, but were there only a few levels? At first it would go to a new level every 500 points, but then it stopped. If nothing makes it harder from then on, it could get a bit boring. Also, it's a little repetitive. You should add other things that are differently shaped and move in a different way or something. Other than that, there isn't much else for me to complain about. Good job, and keep working! :)
