Excellent idea for a game. This is like a breath of fresh air to the platformer games. The graphics look good. The music is very good and fits well to the game. Overall maybe bit on the easy side but there were some challenging levels and trying to beat the times does add more challenge but on my first run by I was more interested in completing the levels. I enjoyed this game very much. Good job.
Very neat concept, and it genuinely felt like a very simple 2D Tony Hawk game (hitting the line exactly right). My only suggestions are more variety in the graphics (different cities/locations), more complexity in the controls (tricks? or even slightly more interesting wall jump controls) and more elements in a level. Maybe ramps or quarter-pipes?
Still, it's neat.
