I remember the apple website used to have a special downloads website which had downloads for various pieces of software, including many games. I loved this site to pieces and found many good games there

However, unfortunately it doesn't exist anymore (or at least it is well hidden). There was a game which I am trying to look for again but completely forgotten the name of it.

I can't remember that well, but you played as a red ballish person and you had to transverse this flat 3D world sort of thing...

Does anyone remember that at all? If so, what are they called x3
