Im sure it is deleted, but I still memorize the physics of this game and how it worked.
It was a fairly popular physics game, where you had this circle-character who had to go to this exit, and in order to do that; you need to make the circle-shaped character fly or move by pushing it with blocks or making it fly with swing physics. I remember there being three types of blocks in this game, wood; which can be cut and moved by a change in the general balance of physics. Stone; which cannot be cut but can still move, and brick which cannot be cut or moved. There was a level editor and many people were creating levels; and there was a main level progress up to 100 i believe.
