Guest or Ghost

The hotel takes only monsters. Your job at the front desk is to tell them apart from the humans sneaking in behind their faces.
Every guest hands over a card and a briefcase. Take their temperature, read their pulse, measure their scream, check their blood type and look through their luggage. Five clues, one verdict: hand over the room key, or press the red button and let the demon take them away.
While you decide, the line grows and loses patience, room service orders stack up on the screen, and the hotel computer freezes, fills with pop-ups and dies at the worst possible moment.
At the end of every night the guests write their reviews. The stars decide how busy tomorrow gets. Three bad nights in a row and the hotel closes for good.
Features
A front desk you work with your own hands: tools, keys, briefcase, chest and platter.

Five clues per guest, and no two nights the same.

Room service running in parallel with the line at the desk.

A computer that breaks down on its own and has to be hit or restarted.

Endless nights that get harder the better you do.
