Here are three test versions of the game. BEWARE! they are beyond alpha, they're so alpha they're omega!
There is no real collision between you and the large sphere you are "standing" on. So you can go through it, however if you go above it you will slowly float down, like there is some sort of gravity, and there kind of is.
there is also a stack of blocks to which you can orientate your self to so you don't feel so lost with out any landscape to get your bearings with.
