Okay, I have to ask, are you and Zelmax the same person, or are you just coincidentally working on the exact same style of game with the exact same control scheme and pre-fab sprites?
Also, if you tap Jump on the springs, you get a massively boosted jump—in Level 3, you can use this to get on top of the cliff at the start and walk off the leftmost edge, falling forever. You may want to either find a way to include a "death plane", or make that cliff part much much higher, or add an invisible wall of some kind.
