The game system in Five Nights at Pokémon's is very similar to the original version. Your job is to watch over the restaurant at night; you can't move from your desk, but you control the surveillance cameras and security gates. This means you can look at what's going on in a certain room or close the doors to protect yourself at any time.
The main differences between Five Nights at Pokémon's and Five Nights at Freddy's are the evil creatures in the restaurant. In the original game, the creatures are an animatronic bear and his gang of bloodthirsty friends, while in this version, you'll see worn-down and beaten-up Pokemon.
Five Nights at Pokémon's is a fun game that is, of course, especially appealing for Pokemon fans, though anyone can get a good scare from the twists and turns in this game.
