Despite being a demo there are some flaws.
-The objects only fall straight down, so there isn't any physics to throw them around with the Physics Manipulation Device Mark 7.
-Some objects (Balls, Laser Turret Things, etc.) disappear if you activate the same button used to spawn in the object.
-There are some bugs (Balls staying in place above a moving platform, the player getting stuck on a platform, etc.)
I honestly hope if there is a full version of this game, it would be a neat portal-type game
