i think its cool
Really good! I like it! The player slides, that is why it is 9/10.
Why did you make the character so annoying to control? The more momentum he gets, the harder it is to stop him. He likes to slide. He likes to make these small bounces when landing on ground after a jump. The gravity affects him quite slowly so he also glides in the air. His jump height seems inconsistent. Speaking of the jump height, why are there these climbing parts where at first it seems that you can't reach the ledge, but somehow (bugging against the edge), you do make the jump? Really annoying spots that serve no purpose.
The graphics are alright, although I wish the spiky rocks were more clearly marked. You also use a quite a boring tune that I've heard in like 50 other games. But the word that sums up this game is 'annoying'. The challenge should come from the level design, not from the annoying control of the character.
