Another Princess is in our Castle

This is a Super Mario 64 ispired horror experience. It's currently just a demo, but I'm planning on making it a full game.

Story:

You play as Mario, the hero of the Mushroom Kingdom. You decide to come back to Peach's castle a few years after the princess' death, but something isn't quite right...

Gameplay:

Collect the statuettes all around the castle without getting caught and uncover the mystery!
