Good game, relatively easy
Easy game... that is until the final level. For the most part before it, I played, did simple tricks and beat every level on at most the 3rd try. Then, on the final level it took me about 53 tries. I suggest ramping up the difficulty of the levels earlier on so that the game seems more balanced and challenging. It just seems now like an easy game with a mario world like final level (aka way too hard).
This game needs:
User created levels. This baby was MADE for user content.
Levels that are moderately hard before the final level
Different music
Powerups and upgrades!
Great job, keep it up.
