Remodeled

Here. You wake up from what you're told is a coma. Apparently, your entire life up until now was just a dream; you're here at the Yellow Brick Institute for therapy to help you regain your real memories.

But, no, that's not actually true; you're actually a guinea pig in some creepy experiment. Enjoy!

Tropes used in Remodeled include:

All Just a Dream: What the doctors and nurses at the Institute would have the characters believe.
Beach Episode: Day two.
Convenient Coma: What the staff says the patients were in prior to waking up.
Epileptic Trees: After being at the Institute for less than a day, characters are already thinking up theories about the true nature of their imprisonment.
Fish Out of Water: Everyone.
Fish Out of Temporal Water: Everyone from an earlier time period or less technologically-advanced world.
Jerkass Woobie: Lightning
Laser-Guided Amnesia: After enough therapy sessions, patients will begin to "regain" their "original memories", while losing equivalent memories from their "dreams".
Magnificent Bastard: Lelouch vi Britannia, Ribbons Almark, arguably the warden, Dr Linda Grey.
Nerf: Everyone's powers have been almost completely nerfed.
Quest for Identity: Somewhat experienced by the characters who actually believe the lies about their having amnesia.
There's No Place Like Home: This being a multifandom game, this is obligatory.
"Which Restroom?" Dilemma: Faced by Haru, an intersex character: There are only two dormitory wings, one for male patients and one for female patients.
