Portal 2 chapter 4, Test Chamber 21

Also, (yes, I know I'm necro-ing this thread pretty hard right now) ConvictedofFun, when you play this level in the main game, Wheatley doesn't open up the wall to bail you out until the player is walking on the light bridge toward the dispensed cube sitting on the light bridge. It is by that point that the developers assume the player has figured out the solution to the puzzle (get the cube, put it on the button, and go out the door). So if you made it through the single player game, you practically already solved this one before Wheatley came.

Sorry for the necro. As long as I'm here, I'll just respond to Harry Knuckles a second time and say that if I knew how to use Hammer, I'd probably be able to take the original map and directly modify it that way, to be solvable.

Theoretically, the grid row where the light bridge comes out of should be aligned with the cube dropper, as it was in the game. I think the adjustment that is sometimes needed with this map is because of the limitations of the in-game puzzle maker. It wasn't made by GLaDOS/Valve, after all.

It falls off it for me, i had to move the light bridge after the cube bounced. But its a minor detail. Its a solid level.

If this was what the puzzle was supposed to be like, I would have never beaten that game. That was difficult, really difficult.

Thanks for the comments, guys. Harry, may I ask what you mean by "a little awkward"? As far as I can tell, the cube falls on the light bridge just like it does in the main game.

Well its not much of a puzzle, but glad you decided to let me play what wheatly interuptted.

It was a little awkward to catch the cube on the lightbridge, but overall solid idea.
