Game Description

The player is playing as a Thief trying to steal items from a home that is guarded by its homeowners. With a homeowner on each floor, the player has to maneuver around them by hiding, taking stairs, and taking elevators. The goal of the game is to steal as many items as possible, which increases the player’s score as that is what tracks the player’s progress.

The thief (player) has to successfully steal as many items as possible with the highest value as possible without getting caught by a security guard/homeowner. To steal these items, the player can pick them up by walking up to them. With the items the player has successfully stolen, they can sell the items for money which can be used to upgrade the Thief’s stats like inventory space and speed.
