On-topic: This does require a serious amount of wall jumping, right? I suck when doing it on a keyboard.
Yes. Walljumping and (IIRC) single-wall walljumping are necessities. Crumblejumping is optional, but necessary for a 1% run. At least you don't need HBJ!
It appears that Double Helix may be getting one [IPS patcher/creator], though...
Let's hope it doesn't have disastrous patching results as SMILE did, believe me, patching through that fucked my patched ROMs up a lot, had to replace those and used Lunar IPS.
