It seems you took some inspiration from Super Meat Boy.
The game was really hard. It would have been nice if you could retry the level you just failed at. Having to start back at the beginning is a little frustrating and then not even getting the same second level the second time makes it very hard to learn how to beat the levels. It would be nice if the levels were in order and increased the difficulty a little at a time.
Edit: Actually, this just dawned on me today. The levels are all random because the theme was surprise. Sorry, I totally missed that yesterday.
The saw graphics were pretty good and the particle effects were nice, but maybe a little bit too much.
