Yume 2 kki/YMMV

"Uh-Heeeee-hee-heeheeh-hee...!"
 * Ensemble Darkhorse: There's so many memorable characters it's hard to list them all. Many of them get wallpapers depicting them as well.
 * Urotsuki herself counts, in fact she's depicted hanging out with Madotsuki the most out of any fan game character period
 * Goddamn Bats: About 6 different ones, the worst being the snake women, who also like to steal your hard-earned money.
 * Good Bad Bug: Locations that restrict the use of the Bike do not restrict Wolf+Bike..
 * Memetic Mutation: One of the effects/characters, the so-called Strangler Eyes, added in version .095, has become a meme on Pixiv.
 * Nightmare Fuel:
 * A boarded-up doorway which you can chainsaw through. You find yourself in a puke-green hallway with black stains all over the walls. At the end of the hallway? A giant Uboa-lookalike that sits on a bed and laughs creepily at you. Gah! Here's a video. And then (in some versions) there's what happens when you use the Telephone effect.
 * The creepy clown inside a circus tent. (video link)
