I really liked this game. Even if it's not 'finished' as such, it's still an interesting story that leaves a lot of room for interpretation.
The controls are very nice too and I have never felt this worried about a rectangle before.
Kind of reminds me of the movie Event Horizon.
I enjoyed it. I like how the story sort of slowly developed. Good atmosphere, too, especially when the music cuts. Feels like something's going to come at you any moment. The secret pickup was awesome, as, apparently, am I. The ending was a bit abrupt, but that's my only complaint.
What did I do?!
Great game, very nice ambiance, I just don't get what happened when I jumped through that hole.. Was I supposed to be there?
This was a very eerie game, and the tense atmosphere it portrayed was simply fantastic. The ending, while unexpected, really does fit the game rather well. I couldn't help but get the feeling that, after all this time, the player was actually the creature.
After reading the post-mortem, I sincerely hope that you do decide to make a "fleshed-out" version of this game.
