Aperture Class A Puzzle (Lengthy)

A very long and somewhat difficult puzzle.

First puzzle is on your left when you exit, it contains an a portal room and a puzzle room. Once you complete the first puzzle on the left the laser on the right will go down, complete the right puzzle to unlock the centre puzzle. The exit is on the top right of the centre puzzle.

Thanks to Mrminion07 for being my sla- *tester*, he was paid in a single piece of gum for 2 days of work.
Recently fixed up level so there are no more mistakes.

(Change Note: After 10 Oct the cubes WILL re spawn if you mess up and get it destroyed.)

(P.s. If you have trouble with the level, it most probably isn't the level being poorly designed. All cubes that rely on tractor beams can be reset if you miss your mark.)
