It begins with a man named Daniel waking up one day without a reflection. It turns out that having a reflection is the only thing preventing people from passing through the mirror and ending up in the mirror world on the other side. Daniel meets a reflection named llehctiM, and the two of them start on a journey to find their other selves.
Puzzles revolve around manipulating items from both worlds. The mirror world is a great way to get duplicates of items. It can also cause trouble as the mirror world is falling apart in any area without a mirror, destroying important items and blocking some paths with rubble.
This game provides examples of:
- Abandoned Hospital: The east wing of the asylum in chapter 2.
- Dream Intro: The game starts with a scene that Daniel perceives as being a dream.
- Dual-World Gameplay: It is important to find and manipulate items from both the normal world and the mirror world to solve the puzzles.
- Fantastically Indifferent: Daniel's reaction to losing his reflection is basically "well, how am I supposed to shave now?"
- Heart in the Wrong Place: Unbound reflections can be distinguished from original people by the position of their hearts. Originals will have their hearts on the left side and reflections on the right. The two groups even call each other "righties" and "lefties," referring to this difference.
- Hint System: There's usually someone Daniel can talk to to get a hint of what to do next. In Chapter 1, it's llehctiM that fills this role.
- Informing the Fourth Wall: As with most adventure games, Daniel does this when examining objects or when combining or using items. There are a lot of reactions specific to particular items and combinations, which can include hints of the correct object to use.
- Kleptomaniac Hero: As a general rule, it's okay to take anything from the mirror world, as long as its removal won't hurt any of the reflections when they try to mimic what's going on in the real world.
- Lock and Key Puzzle: There are a few puzzles like this. Frequently the key is from the wrong world, and Daniel needs to find some way to flip it.
- Man In The Mirror Talks Back: In Chapter 2, geM and Meg can be seen having a conversation with each other through a mirror.
- Mirror World: The world on the other side of the mirror, obviously.
- Missing Secret: In Chapter 1, there's a pair of socks that go in your inventory and do nothing. They're supposed to be a hint that you need a pair of the more useful thermal socks.
- Poor Communication Kills: In Chapter 2, Daniel helps llehctiM meet with someone that can help him find Mitchell. geM was trying to prevent llehctiM from finding Mitchell since Mitchell probably tried to kill llehctiM, but she didn't tell Daniel this because she didn't trust him.
- Sdrawkcab Name: People from the mirror world use the original's name spelled backwards to differentiate themselves. They even put the capital letter at the end.
- Wainscot World: The mirror world exists on the other side of any mirror in the original world and is populated by people who act exactly like their reflections... except in the event of a splitting. Furthermore, unbound righties and lefties also have their own society within the mirror world.
- Unusually Uninteresting Sight: People in the mirror world don't react to Daniel because reflections still bound to their original will only react to things happening in the original world. This lets him sneak into places he wouldn't otherwise be allowed to go.
- You Shouldn't Know This Already: There are some items that Daniel will refuse to pick up before it becomes apparent that they're relevant, such as a family photo that he won't pick up until he sees that it's missing in the reflection world.
