Simulacra 3 is out now, and it’s the third entry in a horror game series involving phones and spooky going-ons courtesy of Malaysian developer Kaigan Games.

The game takes place in Stonecreek where people are vanishing into thin air. You play an intern who has to get to the bottom of this spooky mystery by helping journalist Ruby Myers with the paperwork. So all the action takes place on the phone. It’s pretty intense stuff seeing your actions play out in real time.

If you’re stumped, here’s a video walkthrough on how to solve the game’s puzzles.
