Unlike modern versions which utilize complex fixed-room templates, v1.0.2 utilized a simplistic Random Walk Algorithm or a basic BSP (Binary Space Partitioning) tree.
In version 1.0.2, the antagonist (commonly referred to as the "Ghost" or "Krasue") operates on a simplified Finite State Machine (FSM):
Technical Note: Players of v1.0.2 often report the "Floating glitch." Because collision meshes on doors were occasionally unoptimized in this build, the ghost could phase through specific door frames if the player closed the door on the entity, a bug patched in later versions.

Version 1.0.2 represents the "vanilla" era of Eyes, prior to the introduction of multiple monsters, the multi-floor hospital layout, and the "Chica" character. This version is characterized by a singular, single-floor procedural map and a minimalist approach to environmental storytelling.

Veteran players memorized which “seeds” of the mansion had these death traps.
In Version 1.0.2, you are a thief with a single, desperate goal: break into a procedurally generated mansion, collect a set number of glowing eyes (the in-game currency), and escape through the portal that spawns randomly. That’s it. No tutorial. No map. No stamina bar that refills magically. The mansion is a labyrinth of identical hallways, grandfather clocks, and paintings that seem to watch you. the multi-floor hospital layout
The aesthetic is deliberately drab: low-resolution textures, flickering torchlight, and a pervasive gray-blue fog that clings to the floor. Unlike later versions, 1.0.2 had no ambient music—only the sound of your own footsteps, the creak of floorboards, and the distant, guttural breathing of the entity.
