It's a bit bare bones, but it looks very nice! I love your sprite work for the characters in particular.
It's a bit odd to have a volume slider for music when your game doesn't appear to have music. (Unless it just changes Nerissa's singing?)
I was kind of unclear what had happened with Bijou, I thought she had sent me back to the character select with her brainrot powers or something. I would've liked to see more variance from the fights though. Essentially all of them are solved with by [walk up, attack, walk away]
...Deez nuts.
