That was a great game :D To solve the floor issue, I would just scale the cube from the bottom and not the middle (Make an empty game object, place it at feet, drag the cube in it, scale the empty game object) You could even experiment with other sizes, maybe instead of a 2 high cube, also have a 2 wide cube thats 1 tall. and then a 2 by 2 cube thats just a BEAST
