This is absolutely great. I love the art style, though the black and white is a bit irritating.
Movement looks amazing, I cant imagine the amount of work you must have put into this.

What I love most though is that you really captured the principle of an arcade platformer: Taking a few simple elements, and then combining them to create a never ending variation of gameplay. For example, I loved the huge wheels with the saw elements and that stuff. Also, every level seemed to offer a new, unique idea and solution, what I think is absolutely amazing. If all 50 levels fit the quality of what is shown in the vid, I'd even pay for that game. Really amazing work.
