How to play

The goal: cross the compound from the west pad to the green exit gate in the south-east without maxing the suspicion meter. Guards walk fixed routes and scan with 45° vision cones; their sight is blocked by walls and crates.

Look / cameraMouse — click the scene to grab the pointer, or drag
RunShift — fast, but louder and easier to spot
CrouchC / Ctrl — slow, and guards see you at half distance

PhoneLeft joystick to move, drag the right side to look, RUN and CROUCH buttons

Winning: step onto the gate pad. Losing: suspicion hits 100%, a chasing guard catches you, and bumping into a guard in the dark is a very bad idea. Score = shards × 100 + 300 for escaping + a time bonus.
