This was a quirky kinetic novel!
I enjoyed the characters. They had good designs, and fun personalities that bounced nicely off each other. The story never took itself too seriously, starting with the Wumpus (now there's a vintage reference!) and continuing on with puns, gags, and references. It was maybe a touch sillier than I expected... not really a criticism though.
I did have trouble judging what era the setting was supposed to be. I thought it was Victorian, but then the backgrounds seemed more modern. Maybe it's a fantasy/alt reality setting? (Beyond just the presence of Magical Girls)
I like interactive elements when I read visual novels, but I do understand that this is meant to be a kinetic novel. The length felt about right for what was there, but I did find myself wishing there was just a bit more story. It seemed this novel was more focused on just the interaction of the 4 characters. Maybe an encounter with the Wumpus or some other action/drama could spice it up a little.
Still, I enjoyed my time reading this. Nice work!
