Just from the video:
I couldn't really see the obstacle lasers
Most rooms looked the same
All of them looked rather trivial in difficulty
With the mechanics you do have, you could design some pretty complex obstacles. The showcase video looks mostly like empty rooms. I see promise in the movement, it just needs to be faster.
One important aspect I cant tell from the video is controls. They will most definitely make it if they are silky smooth and intuitive like Mirror's Edge or absolutely ruin the experience if they are clunky.
