Solid game! I'm sure this isn't anything you haven't already heard, given the number of comments already, but the camera should definitely be zoomed out more so you can see where you're going. It should also track the character much faster (or even just not be smooth at all) so that your character isn't on the far right of the screen when you're moving forward. Both of these changes would make it much more enjoyable to play!
Aside from that, nice work!
