Type: a crossover fan game - Mario in the FNAF format
Goal: five nights as the pizzeria guard
Threat: Mario, rebuilt as an animatronic
Difficulty: high, and it does not ease you in
Cost: free in the browser
Super Mario wants revenge and turns into an animatronic in FNAF Super Mario. This time you are the night guard of the pizzeria, where something strange happens after dark. Work out what it is, and try not to panic - otherwise you start the whole thing over. Not everyone gets through this one.
Gameplay
The gameplay is difficult, and the harder part is holding your nerve as the tension builds. Spend five nights in a pizzeria with an animatronic Mario who will absolutely reach you if you stop paying attention.
What carries over from FNAF, and what does not
The five-night structure and the office are straight out of the original
The cast is not, and the familiar patterns do not apply to it
Restarting from night one after a loss is what makes it feel hard
If you want the version with rules you can learn, that is FNAF 1
