Changelog: a6 to a7
Choke is a tiny bit higher.
Made it easier to realize you can't shoot above the metal beam
Fixed the game-breaking shutter door bug on last.
Hopefully these this version has no gamebreaking bugs. I'm aware that the roofs on mid and last may be hard to realize which of them you can't stand on, but I'll work on that for the beta version. You just have to test it for now.
