I think I beat this in about 7 minutes, and only because I didn't see something I could grab in the very beginning. I agree with a lot of what DreamBones said, especially about this feeling like one of those old flash games we'd find on those old gaming sites (that are sadly not around anymore...).
This is absolutely horrible in all the best ways. I do NOT mean the game is horrible, far from it. This was enjoyable to play and I love that we're put in the role of what appears to be the antagonist. I wish we could have found notes or tidbits about previous owners and what might have happened to them, and I also wish the game were a bit longer, too. I really enjoyed the light world/dark world mechanics. I felt that just having a dark world really set the tone for the game.
