In a remote town, there was a bus driver. He drove a bus from one stop to another, sold tickets, took money, and gave change. Then they came - shapeshifters. They were almost like regular people, but there was always something off about them. 

Some had weird skin, some didn't know the basics of this world, and some wouldn't even answer a single question. But not everyone is easy to spot. Some are extremely convincing. You have a set of tools to test them before they can take a ride on your bus. You can X-ray them, ask questions, measure their temperature, and run many other tests. If a shapeshifter hops on the bus, they can slotter the regular passenger. Nobody wants that, so pay attention.

Key features:

• Measure temperature with a thermometer

• Look at the body with an X-ray light

• Ask the passenger about they apperance

• Decide whether you should give a ticket or not

• Drive passengers to stops where they want

• Earn money to get new buses and upgrades
