Fine.
Seems like a good idea, I don't know what will the "bird bread" be for, but it's got a lot of posibilities. Now, the gravity is to low, and the main character runs to slow too. If that has a pourpose to make the game more interesting its fine, else, you should work that out.
I don't know about your programming skills, but another detail that may give it a nice touch, would be that the flying hat looked as it was dragging the stickman. Just like the helicopter games, when you turn around, the helicopter tilts (So, the flyerman ... or flyingman could tilt or his legs could be delayed for that pourpose.
By the way: keep those messages on the sky. If the player isn't busy evading enemies or racing against time, they may be great.
Hope your game turns entertaining at the end. Keep the good work. Read ya later.
