Hey man, I did my full 10-minute review during my Twitch Stream last night (twitch.tv/aaknox), but I'm going to summarize what I said during my review:
Art: It was ok. I could tell what something was suppose to be by looking at it.
Animations and Controls: Animations were good. Controls and game physics were frustrating (but that's the point of a rage platformer).
Sounds and Music: The sound is good. Fits the overall feel of the game.
Overall gameplay: The only thing that you misses on is the fact that games need a balance learning curve for the players in order to understand the point of raging. I think if you made a tutorial level that eased the player into the game mechanics before you threw us into the pits of this rage platformer, then I will be okay with raging through this game.
Hope this review helps you grow!
