Scepheo, it would be nice if in your submission text you explained how eversion works for the newbies, and how you pulled off that floating glitch.
I suppose any% is too simple a goal for this game, though I'm not sure I totally agree with Kelly that a TAS needs to "look like a TAS"
One note I remember from playing this myself was that the gem counter at the beginning of level 7 doesn't update until you re-enter the level, which forces you to quit back to the title and re-select level 7 to access the 7-8 portal if you get your last gem there. That's probably
the only time that restarting a level helps you anyway, but it's a good technique to keep in mind. Also don't forget to look up maps of the game (There's even a level editor you can use!), as you may find an eversion portal you didn't know about, like the 5-6 portals situated over thorn pits which require a bit of good timing to use safely. And be on the lookout for portals whose area extends a bit beyond where you were intended to be able to reach them from, like the 2-3 portal in level 7 you can touch from the underside. As for luck manipulation... I think the flying hands pick random altitudes?
Oh yeah, do you think any other version of this game deserves a run of some kind? The earlier versions have a different level 8 with forced eversions to random layers, and other little things were changed, like I think you could run past the right edge of the screen when you're chased by bubbles and get hidden for a while; I wonder what happens if you go far enough like that.
