Nice
Well, you've got some beautiful backgrounds, some cheesy jokes and that should make an excellent game. But I'm sorry to say point and click don't work that great anymore. Since even shooter games offer a cinematic experience, solving a mystery in a leghty manner is not that appealing. Also the beaty of old point&click was that almost every action was animated with great care.
Your game is great but at the same time a little weaker than original games like that. Look at the revamped Sam&Max they've added some arcade elements so it is more entertaining.
Oh, the accident joke went like this: when clicking 'upstairs' character would reply "we don't go upstairs... <silence>... not since the accident" - that moment of silence had a great impact. Also a retold joke is not that funny anymore. And the joke "Lower, lower, oh, too low" was from Futurama
Maybe invent some totally new material?
