Nice job! Don't know if it was intended, but the terrain movement with the camera is super disorientating but honestly, a cool effect. I might've missed it but putting controls somewhere would've helped - and a way back to the main menu from the game. If you're going to expand on this, I would try to incorporate mouse input or something for the right hand to do - it was a lot on one hand. I think it's a cool concept though - glad to see others tried the 2D/3D mix!
