Wow, you're fast, Tmast98!

WAIT! Forget my previous comment. I messed up. (Aperture looks bad in the BEGINNING of the game, and better in the end. These puzzles are assuming that aperture will fall apart again after the events of the game. My mistake!)

The overgrowth is the future, the clean is the past :)

Great concept! Only one problem: Things I do in the future influence the past... shouldn't that be the other way around?

Well done, I enjoyed it. I really like the explosions.

Well, cool map, but i a bit cheated to solve it ^^'. In fact it's possible to NOT destroy the turrets in front of the final door. I just rushed exactly when they are "going to sleep".

Medium difficulty. The time switchign thing definately made it more trickey.
