is there any way to switch the direction of gravity?

Well, if you constantly push the player up the Y axis with a small amount of force, you get can get the effect of having the player "fall" upward. If you want the player to be flipped too, then just rotate the head. The player should still be able to air control his way around the map, so long as there isn't any bumps in this way.

thanks! that will really help!
