I've been playing this offline, aiming for a sub-20 on Glitchless Any% without watching any existing runs. Now that I got it, it's good enough to submit. I'm not sure if I'm going to keep running it, but I think I could get a sub-19 with a cleaner Warp Zone. Any further than that is going to require learning strats and getting gud at Gravitron.

Resubmitting due to incorrect platform (Steam, not Switch).
