It's far from bad, but it needs a bit of work all around. The movement felt clunky, managing the inventory was unpleasant, the puzzles we're a bit simple, and the character of the cop painted him as a pretty bad cop. I mean, not knocking, breaking in, ransacking and picking up random loot, and taking out his gun and shooting someone on site who he could reasonably assume was the girl's father was just the icing on top of the "bad cop" cake. That isn't nessicarally a bad thing if he's intentionally a bad cop, but ya know, if he isn't, it is.
That said, I like the style and tone, and would like to see you improve, this is far from bad, just lacking and overly short, even for a demo.
