The wumpus line does a great job of setting the tone early on. Ellie is probably my favourite, but all the characters have amazing chemistry and great lines. The character art is great, too, both the designs and the drawings themselves. Wanda reminds me a bit of Bean from Disenchantment because of her hair colour and expression.
I'm less of a fan of the backgrounds, in most cases I can squint and say, yup, that's a fantasy Victorian England, but there's also one with a modern city bus or delivery truck visible in it. I do like the setting but I also feel it isn't being fully utilized here.
The meta ending kind of works for me. It still feels like a "crap we're out of time and ideas and we need to end it" ending, but it's executed better than most, and just barely slides by on the chemistry of the characters. The Super Monkey Ball reference is also appreciated.
There are two minor issues that take away from the overall polished appearance a bit; there's some visual weirdness with the border of the text box, and some of the transitions reveal that the character graphics have no legs.
I'm also on the fence about having both music and ambiance playing at the same time.
Generally I'm not a fan of kinetic novels- I expect games to have gameplay (bit of a cheap shot, sorry). This one I liked the art and writing enough to get by but I think if it was much longer I would start to get frustrated.
Overall one of my favourites of the entries I've played so far (though I've only played a quarter of them I think).
EDIT: I do like that the themes were worked into the girls' powers, but it did come across as just a bit ham-fisted.
