Inspired by Kaizo hacks and insane Mario Maker stages, this is the hardest test chamber I have ever made. The ridiculously masochistic portaling techniques required make Portal Prelude look like a joke. Quick-saves are basically required.

I actually died a bunch of times but the failures were edited out (hence the slight jump-cuts in places), otherwise the video would have been way too long to hold your attention. Now that I think about it, I kinda wonder if it might have been better to leave in each unique death/failure.
