Fun little Jetpack Joyride type game! At first I didn't know how to start (didn't see the game page) and my keyboard is a 60% keyboard so I have a hard time playing games that only move with the arrow keys...
I'd prefer it if you added WASD aswell maybe?
And also I think the character changes direction a little too fast. I think the controls would feel better (to me) if you used a rigidbody and used AddForce() on the character.
But still, great!
