Oh :-[ Im sorry you found this game that bad.
We want everybody to love our games!!
Like Dave Grossman said, at one point adventure games shifted from puzzle games with stories to story games with puzzles. Demonic Dollhouse felt more like a puzzle game with story, it's fine if you like these games (like I do) but I understand that not everyone will like them. In adventure games, rewards come in the form of expending the story, meeting new characters, exploring new locations and/or finding jokes hidden all over the place. An adventure game without rewards is a bit like one of those challenging and punishing platforming game, many like them but many do not too.
Regarding the game, I thought the game was cool if a bit short, I agree with jkohen regarding verbal feedback, more verbal feedback (hints, jokes, etc.) would have been nice. If you were to make a sequel, with more demons and in a bigger house, I would play it right away but I know I'm in the minority so I'm not holding my breath. Keep up the good work, I can't wait for Death Episode 2!
