Ok.
Your interface needs work. You can't switch between items easily and you should (read: need to) be able to switch between Move, Use and Examine by pressing the M, U, and E keys. Other than that, it doesn't look very pretty, but that's something to worry about in the final version.
Story was cliched to fuck with the guy waking up like that, so I hope that's not what you have planned for the full game. And don't tell me "oh I'll make it so it's not cliche". No you won't. Amnesiacs and waking up in strange places are so overdone it's not even funny.
Puzzles were terrible, but that's probably just because you made it in a few hours. The thing to remember for a final version is that if any of the puzzles require the player to use meta-game logic (ie, to include the fact that they're playing a video game in their working-out of what to do next), that's a massive downfall. Just put yourself in the shoes of the protagonist: if you found a dirty toilet, why the fuck would you clean it? What the hell was that supposed to do? The only reason I thought of doing it was meta-game thinking: it's a game, so there's bound to be a solution if I just keep doing random stuff.
The drawings of inanimate objects were sort of interesting, though it was difficult to work out what they were sometimes. The drawings of people, on the other hand, were pathetically terrible. They were also plagiarized. You can say "oh I'm just working within the Anime style" - but you're not. You are being unoriginal, bland, and irritating. That's all. Although honestly the unoriginal art wouldn't be so bad if you were at least better at drawing it.
The music was nice.
To summarize: it's alright, for a demo. 4/10 | 2/5.
