The plot of Doors revolves around a seemingly normal, happily married couple who have adopted four children. You play as , the second-oldest son, navigating a world filled with:

changes the rules. You are no longer just an observer opening doors. You are now a participant in a "correction protocol." The v036 environment has begun to glitch, and the doors are starting to remember you. The tagline printed on the game’s splash screen says it all: “You opened 36 doors last time. Now, the doors open you.”

While much of the game focuses on romance and adult themes, it also delves into "dark secrets" and the consequences of past decisions, maintaining a high level of character development.

Before diving into the corridors, let's clarify the terminology. "Doors v036" refers to a specific build or version of The Neuron Project’s ongoing series about liminal spaces and decision theory. Part 1 introduced players to a seemingly infinite hotel hallway with 1,000 doors. The twist? Each door led not to a room, but to another hallway with 1,000 more doors, creating a fractal of anxiety.

While the developer has not released an exhaustive changelog for every sub-patch, this update generally focuses on: Expanding existing character arcs.
