Mechanics: 4/10 unorigional, puzzle platformers have used this flip tool many times.
Controls: 2/10 unresponsive, laggy at best. tended to have little control when falling, particularly notable during the "digging" level.
Music 6/10 music seemed to fit the situation
Story 6/10 caught my attention, engaging, if a little unexplained
Work on the controls and add some "new" mechanics and you've got a good looking game
