Reminds me of Moto Racer, an old Microsoft Windows game. Like the others said 1) The difficulty is pretty easy, 2) Camera issues include crashing and being low to the ground so that you can't see upcoming turns at times 3) I recommend adding challenge in terms of time it takes to get to each checkpoint, like a count down or having a trophy system in terms of finish times. Not a bad game, but a good working start.
