Impostor Syndrome made me squirm at the chair, the music and that cool black and white space-ambiance gives me the creeps.
The puzzles are intuitive and well designed; but I couldn't concentrate too much, because I was using my 5-sense staying alert!
I played this game 2 or 3 hours ago, once played, the gameplay sensations that remains in me are a mix between: "Don't cross this door, don't even think about looking back, please quit the game and prevent a hearth-attack" + "Man, be realistic, this is just a game, it couldn't be that bad!".
I suppose the game was as "fun" as an horror game can be ^^'
Highly recommended
