G-Switch

MHere is a game where you need to battle not against enemies – but against the force of gravity! You can reverse the direction of gravity by pressing any key. In every other respect, this is a lot like every other platform game you’ve played. You can’t cheat by changing direction in mid-air, so you’ll need to plan your jumps in advance if you want to avoid flying off into oblivion (or getting left behind by the ever-scrolling screen). There’s a multiplayer component to this game, too: head to the multiplayer section in the main menu and shift the player count up to as many as you have available.
