The aesthetics of this game! The aesthetics of this game! Uuhuhuhuhuhuhuhu! Wonderful.
It has an atmosphere very well terrifying that gives you good paranoic creeps. Maybe you can get some claustrophobic feeling too. Now, the freaking hauntings that appears in this game are quite disturbing, but the ways they show up are the best: super scary. The one who appears outside your bedroom's window is the best.
At very last, I really want (need) a full game from it. It can even be a walk-simulator, no problem - since it explores the best of its possibilities.
Congratulations.
