I made a horror game in a week

A developer documents building a horror game inspired by the mobile game Granny in one week using Unreal Engine 5. The project covers level design using a school asset pack, a key-and-lock puzzle system, an NPC behavior tree with sight and sound investigation, PS1-style visuals with baked lighting, and custom character modeling and animation in Blender. The post walks through practical solutions to common game dev problems like door collision, NPC pathfinding bugs, and performance optimization via instanced meshes.
