It's a level that was pre-beta that I think only me, builderboy, and leafiness played. But yeah, it's definitely going into the preliminary release, so you'll get to play it too.

It's a bit hard to see that its a person, and you can't see the portals either, could there be a way to take the part of the screenshot where it is slowed down and use that to make it a bit more recognizable?  Maybe speeding up/slowing down the gif as necessary?
