Jill route should have had the bee costume and the others the banana its like DPC punished Jill Fans with the banana costume lol
I believe it is as it should be. Jill is the innocent, sweet, clumsy, goofy, vanilla, basic bitch, semi-mature and so on route, which is somewhat comedic.
The whole banana thing is on point with her route. I had a damn good laugh, and that's what I expected out of her route.
You don't play Jill route because you expect her to say:
Jill: "Oh Asteroid Daddy, ELE(extinction level event) me plz"
MC: "Imma destroy Uranus"
You play it for the vanilla romance and to hit Tybalt as often as you can.
