Fantastic game! I loved the mystery and the process of searching the index boxes, and the story itself is so compelling! I didn't experience any bugs, and while the controls are minimal, I do like that it doesn't hold your hand throughout the game. It really does leave you with the tools and you have to figure out what you're meant to do (granted, I do see how this could be frustrating for some). The atmosphere was also well-executed, and the deeper I got into the mystery, the more chilling it felt. I won't spoil it, but it's certainly creepy. 

Highly recommend this for anyone who likes mystery games where you're expected to write notes, sifting through documents and a some chilling lore that reveals just enough to get you spooked.
