Portal 2 is one of my favorite games. Here are all the custom levels I've made for it.
Chamber 21 (the "accent beyond her range of hearing" one), interestingly enough, has an actual, solvable puzzle (albeit not a particularly difficult one), even though it gets cut short by Wheatley.
The test chamber created in the "Portal 2 Perpetual Testing Initiative" trailer.
what was she thinking when she built this tbh
...and that's it for now.
