Imagine that you had to get a job as a security guard in a hotel. However, already on the first watch, it became clear that something strange was happening in the building, and monsters from nightmares - animatronic robots - were hiding around every corner. Your task, controlling only the mouse, is to monitor all the corridors of the hotel and, at the slightest danger, abruptly lock the doors. Fortunately, there are security cameras on the floors. But be careful, the supply of electricity in the battery is not infinite. Spend it sparingly, otherwise very soon the doors will stop working and the lights will turn on.
