oh... well. i dont even know. hah.

That website is pretty deceiving i went to it, tested it out. the walkable null works but you cant walk on the water fluently. The unit reacts the same when a bunch of zerglings are on top of each other trying to get room, but you have less control of where they go. Its pretty cool though, using it along with some sprites could make a pretty cool map.

i tested the installation tile and it works fine.
