Really enjoyed this one, great music and great atmosphere. The gameplay got repetitive after a while, but the story kept me interested. One problem that really confused me: at the very start the background image is put upfront, so you can't see the player, but once you move away it works fine.

Same issue here with the background image. I like the background and animation style within that. But it can be really frustrating to hit those small things with their super snappy spontaneous movement :).

What what? Gamemovement: just LMB? Ah and mouse. I was curious how it would work out. It makes the game controls very intuitive, but also very hard.
Bu I don't want to dwell on the negative because the game has a great mood, the text, the graphics, the sound and the music all work together to create a great mood. Even the game itself, where you have to work you way up out of the darkness. The darkness makes it a bit harder because you cant see how fast you move or your prey, so maybe a little bit of contrast would have helped (or maybe ruined the mood). You don't have much of a profile. Don't you make more games. judging from what you did here, you should (maybe get someone to check your English).
I don't get why there are so few comments.

I'm really unsure how to begin this one. I'm guessing I get the same issue with the background as described above. Can't figure it out myself.
