Well, your laptop isn't running the game because of the hardware but we are not really sure of the min specs needed. Obviously on your PC it should really work, and we are aware of the varying framerates (which are probably caused by the amount of pieces rolling and such), but optimization is hard and we tried our best within our deadlines.
The camera going through things is something we wanted to fix, but again our time was limited. Anyways, you can invert the camera axis in the pause menu ( Options->Controls ).
Again thanks for your feedback!
