In case anyone wonders:
v1 - Up to half stage 1; barely uses partner switch glitch; easier partner glitch killed it
v2 - Up to final boss; many more tricks missing; ability to start cutscens 18 frames sooner in most rooms killed it
v3 - Up to half 2nd stage; lack of quick partner glitch usage in stage 1 killed it
v4 - Up to quarter 2nd stage; Realization that setting up 60,000+ speed improves a lot of rooms killed it
v5 - 4919 frames faster than v2 by the end of stage 2. Improves 397 frames from v4 by the time it reaches the same point as said WIP
