Granny Prison Horror

Game Overview

Granny Prison Horror places you inside a locked prison environment. Granny can punish small errors immediately, and your job is to assemble a reliable escape route before time, patrols, or lives run out.

Runs are built around door and defense timing under pressure, key-hunting and lock progression, and limited defensive tools that create short openings, so progress depends on controlled decisions instead of panic movement.

How to Play

• Start by mapping nearby rooms and identifying at least one safe retreat loop.
• Collect keys and tools in sequence so each pickup unlocks the next objective cleanly.
• Control line-of-sight and spacing so threats do not trap your route.
• Trigger doors, lights, masks, or tools at the latest safe moment to maximize their value.
• Commit to one escape route per run and complete its item checklist without splitting progress.

Controls

• Mouse - overview
• Mouse Left Button - shoot
• WASD/↑↓←→ - move
