Only saying this cause I haven't seen anyone else point it out and you may not know (I certainly didn't until recently). But the term 'Schizo' is considered an offensive word by many. Do with that information what you will.
I know it's risky, but in 2023 there'll be someone offended by something no matter what... Nevertheless, in this case the term "schizo" is more in the slang for crazy, lunatic... The prefix "schizo" in other languages (I'm Italian and in Italy we do), is also used for someone acting in a frenetic and very "nervous" way, which fits the fast-pace of the game. Furthermore, per extension, the origin of the prefix "skizo" (Greek/Latin) is also for terms like "to split" or "to tear apart", which also fits considering the funny splatter elements of the game. This said, I'd like to point out I don't want to offend anybody with the serious disease of schizophrenia.
