Beautiful game, very good graphics, extraordinary control, great UI and the options I had available (mouse sensitivity) were very helpful.
Now... The game is great, but the ending is not 100% clear, which leaves it open to many interpretations. From this point of view, I had the following problems:
1) If the character died or survived (from the way I saw those bouquets of flowers, I understood that our character died, but while I was on the run, I went through the rooms with the pulse meter and it gave me the impression that walking back from room to room, accompanied by the sound of the heart monitor that was starting to sound better, gave me the impression that I survived).
2) When you run and enter back into the first room, the closet opens and you can go in there. After I entered there, a window appeared with the "Restart" and "Main menu" buttons and I thought I died and that in fact you have no way to escape (it's not really clear when you escape and when you die, maybe you can put 2 endings in which you can put a "good ending" when the character successfully manages to escape from the monster and a "bad ending" when it catches you.
But the game seems perfectly done and finished, it needs a little work on the UI and it will be perfect! :)
