Cool game

There is only music. It is a pity that there is no sound-fx.
There is no scaling of the game screen.

nevertheless, game is fun.

good,

not bad, bike seems to move between heavy and light too easily though, id say make some of the rock obstacles more obvious and you could be on to a 10/10

Raising the bar.

Your graphics are well above par and your physics are clean, which are definitely the biggest points that make or break this kind of game. The controls are somewhat more unforgiving than I like, but that may be a matter of personal taste, and they're consistent enough that I think I'm adapting after a few levels. Your difficulty curve may need work in a few places - level five particularly, you have to come in really perfect to make some of the jumps, and there's no getting back up the shear cliffs if you miss them the first time. A checkpoint system for levels with really difficult jumps both near the beginning and end would be nice, too.

Also, a keyboard shortcut to move to the next level would be a nice touch. It's inconvenient to swap to the mouse every time.

Yeah!

Sweet work brodda :P
