I don't really like this genre as a whole, so I won't give much feedback cause I'm just not into it and that's not your games fault.
The writing is mostly decent, I think some references are a bit too on the nose but also the target audience will probably like this. Jojo is ok, but I think you should change her design to be less like you know who because it feels less like a homage and more like a ripoff.
The art is nice and the sound is good. I think your audience will like it.
