A fun little forwards platformer. I had some performance issues on web as you warned about. I think it could do with some tuning, eg I don't think the jump was quite big enough to jump over the instant death spinners so I died on them a lot. I slipped off the up and down blocks a few times as well, as they were a bit hard to see from the camera angle. The visuals were nice, I liked the 3D environment, and the sound was good too.
