I enjoyed it. The 2D graphics remind me of some of the point-and-click games that came out in the mid to late 90's. The 2D/3D mix was an interesting combo, but I would have liked to see maybe the #d be cel-shaded or something so it matched the art style better.
I had a problem where, seemingly completely at random, the camera and the control scheme would reverse. It made it a bit annoying to move and restricted my view. I don't know if that was meant to be, but if so, please get rid of it!
Besides that, the game is a pretty nifty idea, and a tightening up of the graphics would make a good start for a professional quality game. The per-pixel lighting was a nice and aesthetically pleasing addition.
