Very interesting game, the graphics are beautiful, the mechanics are cool and the sound effects are adequate.
The game has a dark look, but it's still not that scary. Perhaps adding monsters (the authors comment on that) and other elements of surprises.
The camera movement could be smoother and it would also be nice to add a more linear blur over time (blinking), creating a sensation from the beginning that the eye needs to be blinked. I think I could also divide the screen into 2 parts (right and left eye), then I could use the 2 mouse buttons, one for each eye.
Congratulations and success.
