Newton Adventure 1.9: 2d rotating platformer

I made a new release of my game, Newton Adventure, a 2d game which try to combine a classic platformer gameplay and physical elements: in addition of classic walk and jump moves, the player can rotate the levels at 360° giving the game a taste of Super Mario and Monkey Ball mix.
