First of all: If you'll win, it's not depending on skill. It's just pure luck to hit the explosive-barrels or get a punch by a knight. If not, you'll fail it a few meters in front of the goal. Took me 13 tries to have the luck, to barely hit the finish-line. Also no real ending? Shame, because at least, it was a nice game. The rocket - like kapnkennedy mentioned before - is a bit hard to understand. You should fly if you're falling down, use the rocket if you are going upwards & right before you hit the ground, you should get your jumping-ball, because it's also a timed & not by "used by groundhit"-item (what would better fit, i think). Also no view, how high i fly & when i'll hit the ground. Should be visible, because guessing whe, it's the wrong way. Besides of many disadvantages, i liked the game. There are too less launcher-games i like. Maybe you plan a 2nd part with better balanced upgrades, endless-mode & medla-based extra-items? Example: If you fly higher than 2500m, you'll get golden birdwings - allowing to flap a few times - increasing the overall-time you can fly.
