Good start to a game. Love that Marcella isn't a stick of a woman. That Arnie is a bit older himself, makes them more believable as characters. However, your 3d art program is leaving me deep in the creepy side of the uncanny valley. Very reminiscent of Christie's Room or Sharks Lagoon style of games. Not a bad thing, but not necessarily a good thing.
I'd also recommend either a warning concerning sound or a way to turn off the music.
