Aperture Tag SPEEDRUN MOD World Record in 11:52

Well it took forever, but I finally got good at this game. Thanks to Rattle for helping me out with quite a few chambers, diagnosing my lack of skill. If you've never seen speedrun mod for this game, it's very similar to the normal game. The only things changed are no long tube ride/waiting cutscenes, and no dialogue skips at the end of each level.
