Levels are quite nicely designed, challenge is interesting, music is top. But the feeling of speed isn't there. At times, it feels like you're slow even though you're going fast, because there aren't enough indicators in the environments. It makes it difficult to judge jumping distance, and diminishes the enjoyment. 

Still, there's definitely potential there, I'd like to see this game refined

what an awesome game, i bet the creator is very cute and skinny
