good controls, bad design
The level design is terrible, especially when you are given a no win combination of two obstacles close together. However, the controls are quite good. Wheelies are fun to pull off correctly, because there is a bit of a challenge in coordinating your middle and index fingers.
Unfortunately, the bad level design brings the whole game down, and I have to give you a lower score for that. It simply isn't fun to play because the game will give you challenges you cannot overcome.
A suggestion: You should have a bar at the top that shows the positions of both players.
