Fun game!
The only thing I dont like right now is how UP/DOWN is for driving forward/backwards. My brain wants to use LEFT/RIGHT or A/D for that. If I played more, I guess that would be less of a problem.
Id love to see some wiggling or other kinds of physics on the bear and cycle when you land, as it seems a bit stiff at the moment. But the fact that the bear moves relative to your rotation in the air indicates that it wont be too hard for you to implement that :D
