All in all, it's a fun hack. I do enjoy it. As a speedrunner, I do have some gripes with the fixed glitches, such as the Crawfish quick kill. Fixing the quick kills slows down the game, which irritates me, but I understand that the hack was not made with us speedrunners in mind, but rather casual gamers. I also dislike the fact that the boss rush, Doppler, and Sigma are a huge chore as Zero, even with the purple saber. I'd prefer it if Zero got an overpowered one or two shot kill saber for the final stages. It would speed things up considerably. I wouldn't even feel that it would be unbalanced, or anything, since it takes time to charge for the sword, and the optimal saber use is actually difficult. It's kinda dumb that X gets a powerful sword but not Zero, even though it's Zero's weapon and trademark...
If the purple saber was OP, and there was a way to get it for Zero by killing Vile in the factory, and then fighting the Doppler 2 mini boss as X, I would rate the hack way, way higher.
I like the double jump, and I can neon and saber jump as Zero, but the neon doesn't store an extra air dash or double jump, so it's not really that useful. Still cool to neon as Zero, though.
I was able to muster a Zero only any% run in 43:10. There's still a lot to optimize in the route, though. Despite the flaws I listed, it's still fun enough for me to keep working on to optimize. And maybe I'll find new glitches to take advantage of. I feel glitches make these games more fun, so there's no real reason to fix them.https://www.youtube.com/watch?v=m9RZuiV4f24
