Elevator Operator: System ResidueElevator Operator: System Residue

Step into the role of an elevator operator in a mysterious corporate building.

Your job seems simple: pick up employees, take them to their requested floors, and keep the elevator running.

But every passenger has an identity that must be verified.

Check their IDs, personal information, and destination permissions before deciding whether they are who they claim to be. Something is wrong with this building — and not every passenger may be what they seem.

Operate the elevator. Verify your passengers. Detect the anomalies.
