Author Comments:

Two secret agents, Carl and Stanley are on a mission to take back stolen Ruby Gemstones. The gems are spread across the building and they’re guarded by different kinds of robots.
Control Agent Stanley to take the gem in each room without getting caught in the guards’ sight. The guards have different moving behavior and line of sight. You can also use some cool gadgets like Cloaking Spray or Teleporter Gun in certain levels.
This is a turn-based game so you can think as long as you want before making a single step. The guards will only move after you make a move one step at a time. There are more than 30 levels to complete.
