The Sun and Moon

The Sun and Moon, the winner of Ludum Dare 29, is a platformer with a unique mechanic: You can dive into the ground. Momentum is maintained, but gravity is reversed, so you can fling yourself high into the air or deep below the surface. The goal is always simple - collect the three orbs in the level and jump into the wormhole - but spikes, endless drops and impossible heights make this increasingly difficult.
