That's so wierd, cause when I place the portal a certain direction, the ball goes down to the floor, and the other direction, the ball goes up into the ceiling. It was a good map though. Def fun! Will have to try out your next ones :-) Thanks Twolegmike.

Yeah, well. it's not chance. It's portal placement, and putting a cube on a button. You dont have to face certain directions...Anyone who had played Portal 1 should solve this easy.

Solved it, but I don't know. It seems more based on random chance. Facing certain directions when placing portals. I can't imagine most people will be able to solve this, especially since this is supposed to be an intro level to your series. Maybe if this was chamber 2, and you established the basic principle in an earlier version.
