This game manages to build a very creepy atmosphere through the music but also through this surprisingly well lit and empty mansion, something about it just gives me the creeps. The difficult and cryptic puzzle design helped build the gloomy, oppressive atmosphere! I really enjoyed it even if I was kinda stuck towards the end, the walkthrough was a nice addition so I could still experience the game even after being stuck! The puzzle design reminded me of P.T, this whole game has some creepypasta forbidden lost game copy vibe and I love it! Also very good use of the loop mechanic, very original!
