I really like the movement in this game. The flapping mechanic is good, and the jumping and gravity feels really solid. The sound effects fit well with that. Just a lot of fun to move around.
My biggest complaint is with the text. The wave indicators in game as well as the restart text take up too much screen space, and they linger for too long. The writing in menus is a hard-to-read font to me.
I really like what you did with the indicator arrow that points to the wheel, and its tick animation while the wheel spins looks good. The camera motion focusing on the wheel is well-implemented. It would be nice to see what power-up I get if I move away from it after it spins.
To me, some of the gameplay feels a little lacking, but I really like the controls and all the motion you put together.
