Nicely implemented, I think! As many people have noted, the animation is too smooth and not aligning to the pixel grid and so loses adherence points, but other than that the game is fun to play! It's a little difficult to tell when the police officer counts as being in the central room, and I didn't realise for a while that the window is upstairs rather than in the bottom middle at the foot of the stairs, but once I'd worked this out the game was interesting! Good work.
