Gravitorque DX

Great little puzzle game

If you liked Toki Tori, you'll like this. Similar in structure, but uses gravity switching as a mechanic. While not the most challenging puzzle game, it still gives a sense of reward when you beat the later levels.

I Got to Level Eight

Unique Puzzler

A lot of fun with this one. Simple premise of using gravity to reach a goal, but lots of creative ideas on how to make it work.
