I'll also post my high scores on the two main modes rq because why not. I don't really play Sally so I won't include her. I have tried to make Phoebe work more times than I've played Bella, fwiw
Because Itch apparently hates me, I'll have to type the scores out instead of providing screenshots
Full Course:
Phoebe: 357990
Martha: 840390
Bella: 522980
Mixed:
Phoebe: 689140
Martha: 862140
Bella: 798790
I just had a run in Mixed prior to posting this where I tried a lot harder to get value from her powerup to understand what I might be missing- but it still felt like 80% of the time I was fighting against the character.
