Small Complex is a psychological exploration/puzzle game that traps you inside a shrinking, ever-changing labyrinth. The "complex" isn't just a building—it's a reflection of your own memories. In v3.1, the developers have refined the AI of the "Shadows" and added a new "Echo" ending.
One of the community’s biggest pain points was the cryptic save system. In -v3.1-, manual saves and three auto-save slots have been implemented, alongside a “rewind” feature that allows you to undo the last 10 seconds of actions—perfect for those frustrating “soft locks.”
