The game is super fun and the level / enemy variety is impressive. The controls are sharp, but instant acceleration on the player makes it hard to do precise on the small levels. The game has a bit of a learning curve and even after playing for 30min I couldn't finish it, but this is also due to a bug that seems stops generating stages after a certain point. The graphics are really nice and having the orb in the back indicate where the enemies are spawning is a nice touch.
