Not a terrible concept, but the controls were unbearable, and I can't say that there was anything good about this. The foundation was in place, extra points for tricks, avoid rocks, and grab health, but it was pretty much impossible to get anywhere in this without memorizing the rock patterns.
You get no time to react as the screen is very small in comparison to your movement speed, and I couldn't get the tricks to work when I hit a ramp. On top of that you could dip below the trick board and disappear.
Some easy fixes would be: being able to move faster, having a mini map with oncoming rocks, and indicating when you can perform a trick better.
Edit: just realized you move with your cursor not the arrow keys, so the speed thing is less of a problem, however I still couldn't get a trick to work, and there were numerous detection errors on picking up health and bonus points.
