The Cheat%'s for 80 and 100 I don't think are worth it. Cheat% is a meme category so I don't think it needs to be anymore than any Any% thing.
Saveless: I did think about this but its just practical. Since saving and quiting is the main way to regain power and health. Yes you can kill enemy's to get those things back but than you run into the problem that if you die anytime in the run it's over. The run is hard enough as it is with saving.
Glitchless: I also thought about this one. Yes, this would make a good category. Not so much a 100 percent glitchless category. Maybe more of just an Any% (No Power Storage Glitch) where you can take powers out of the tutorial. That would drastically change the current route and still leave all other tricks and glitches for the rest of the run.
