PC game like a horror version of Pokemon Snap: Photograph hallucinations of monsters to make them disappear. When the monsters become real, defend yourself and take more photos to complete your monster dex!

The game is nearly complete other than voice acting, some music, and a tiny bit more polish. Completely playable from start to finish.
