The map generation is really basic, but I like the polygon feel of them, despite clashing with the rond player. Their color scheme are also pleasant.
The gameplay is solid, but became a bit boring to me after a while. I like the look of the enemies, with them being blobs and all. Though their shape is a bit rough and once again clashes with the round objects.
Also the game quickly begins to drop frames after a few levels, I'm guessing because of theamount of enemies and the need to recalculate their shape.
Overall nice :)
