I have a few major critiques, over and above what Cris wrote down below (a solid 3 from me as well). I got about 70% through, and then realized that I just wasn't compelled enough to slowly go through all two-dozen rooms again looking for the pendant slot.
1. I feel like the game engine is a problem looking for a solution. You did some good work putting the top-down 3D character model together, but it doesn't add anything to the game itself aside from slow the transitions from room to room. It's like Chekov's Gun; as a general rule, you shouldn't put a jump button in a game with nothing to jump over, and if the walking about didn't have any challenge to it, you should have just stuck with hot spots to click on.
2. The audio recordings were very difficult to understand; I would have just left a bit of ordinary white noise under them.
3. The house wasn't laid out in an organic fashion, which is part of the reason I had so much trouble navigating. If all the bedrooms were upstairs, for instance, it would have been easier to remember where everything was.
That said, I very much look forward to your next game.
