Couldn't get past the early level where you start to the right on a slope and need to go up to the left. Controls won't let me go anywhere but down and right. jump just slightly halts my tempo and hovers me 1 cm above the slope for 0.3 secs. So pretty much unplayable sorry to say :/ Otherwise, work on the execution a bit, seems like it could be an interesting concept but it just looks very uninteresting, and the physics don't really make sense (why are you sliding across a grey 'concrete' surface as if it was ice? and then a few levels later you stand completely still on a 45 degree slope? Have the environments reflect why this is happening. I would also clean up the intro, tie it in more with the art style of the rest of the game. Looks very tacked on and unpolished right now. I like the music! Good stuff. Some more polish and bug testing and maybe a style re-evaluation and this game could be really cool. Just a wild suggestion, why not have the 'rower' (what is that even?) have like a line of dialogue pop up on every or every other level, saying something mysterious or interesting that hints at what the story/his origin is. Keep working at it! :)
