I like the game
And I think that you did some new things that added some fun to the point and click genre, but I think this game suffers from the same problem that almost every other game in the genre suffers from- it assumes that the player knows more than he does. I had the walkthrough and it still took me a few minutes to realize that the main room at the top of the stairs was even there. Looking through the keyhole was a great element, but how would I know to do that if I wasn't just randomly pointing and clicking? I wish I had a solution, but that's a problem I see with the whole genre, not just your game. As it was, it was a well-made and interesting game, but I think the gameplay problems with that whole category of games should be worked out or the genre shelved forever.
