Hi! I've played your game and its my thoughts about experience:
I like the music in game, but you could add more creepy sounds. After playing two minutes the tension subsides, and it's not so scary to play anymore.
Graphics is the best part of the game. I like it and did not find any misuses.
I would also highlight the mood that the game conveys. First play was good :)
There is only one bug in game, that i saw its game restart. After complete the game and press restart button, i can go through all rooms and jump end it.
In general, the game is not bad and stands out relative to others
