PSYCHE Locke is a short 2D Puzzle/Adventure game, with a dark and dystopian setting, which was created for a community event in 2018.

The main theme of PSYCHE Locke is "Yourself", the concept of identity. The game focuses on Locke, a strange being, a "Psyche", who's trying to retrieve his former self and his lost memories. As a Psyche, Locke has the ability to merge his soul with that of other people, manipulating them. The player can merge with, almost, any NPC he encounters during his playthrough. Possessing someone allows the player to do certain things or talk to certain people, helping him progressing through the game.

PSYCHE Locke is a Puzzle/Adventure game. In order to progress through the game, the player has to use Locke's abilities. Since he's a Psyche, Locke has the ability to merge his soul with that of others, manipulating them and accessing their memories and personalities. 

Manipulating certain people will allow you to progress and do stuff that Locke alone wouldn't be able to do. For instance, taking control of a very slim person will allow Locke to fit inside small air ducts and gain access to new locations. Taking control of a charismatic person will allow you to give orders to someone else, while taking control of a strong person will allow you to move heavy objects around.

At the same time, Locke can access other people's Mind Palaces. That's where all their memories reside, and where you can talk to a specific person face to face, learning what their true fears are and what their personality is like. Someone with a very strong personality may be able to persuade others... or perhaps you can use that people's connections to your advantage.

Investigating the Mind Palaces and merging with other people in order to solve small puzzles are the core mechanics of the game.
