I liked the ambience, the sound effects created a nice tension. I ended up not being able to complete the game because I didn't find any items and the ghosts are very fast, so I gave up after the third game over.
One idea is to make the light directional, which you guide using the mouse, and make the ghosts be seen in the dark with only their eyes in red or white, and then if the light hits them they start hunting you.
Anyway, it has potential. Good job
