You should update the description at the Kongregate page. The instructions tell us to use mouse, but in fact we can use any keyboard button (as described in one of the in-game tips).
Needs a low-quality setting. A lag of a fraction of a second is enough to make the player lose the Reaction mini-game. Also, the Stamina mini-game is BORING.
It kinda looks like Super Meat Boy, with all those saws and dangers, and collectible danger signs (which are like bandages in Meat Boy). But the movement and collisions are worse. Not a bad game, though.
Damn "SHIFT" mode... It switches out of "shift" mini-game right before a hole. When it switches back to that mini-game, it's impossible to react fast enough and I lose.
I played the standard mode and lost after 4 mini-games. Then I started challenge mode, and lost because I didn't know how to play one of the mini-games! Please include the description of each mini-game on ALL game modes.
It's hard to see the drag notes when they are behind another note and the screen has tons of notes. Maybe you should make their shape different, maybe a diamond or a square.
A shadow would help to get more precise jumps.
This game makes me remember Skyroads, and that game did have a good shadow below the spaceship. (actually, I think this game is a mix of Skyroads and Knuckles Chaotix special stage)
