I found the camera very difficult to control with the mouse at times and noticed that when my character is against the wall the jump ability doesn't seem to work - I think if you address these 2 probably relatively minor things you've got a good little game on your hands here (especially if you give the protagonist a Spider Man skin! xD). I like the graphics and the environment a lot, I like the wall-grab/slide mechanic a lot and I enjoyed the level layout and design. Good job man.
