Re:in

Overview
Re:in  is an English fangame made by Gaida the Duck (Twitter, Pixiv ) in RPG Maker 2003. It currently stars Hanatsuki and Tamashitsuki.

Gameplay
Re:in plays like a traditional fangame. You start as Hanatsuki and later unlock Tamashitsuki. Hanatsuki is a girl who refuses to leave her room, instead choosing to peek outside. After unlocking Tamashitsuki through a hidden event, the mirror in the nexus is used to switch characters.

Hanatsuki can only access the two nexus doors to the west, while Tamashitsuki can only access the two to the east. Trying to access the other character's worlds will result in either Hanatsuki refusing or Tamashitsuki peeking.

After unlocking Tamashitsuki, you can no longer save in reality with Hanatsuki.

Effects
Effects are called "Pieces" in this game.
