The graphics are pretty good, although it would have been nice if the main character had a bit of animation. The soundtrack is very pleasant.
The central mechanic of picking up luggage and loading the docks works rather well, although it took me a little while to figure out where I'm supposed to stand to drop off the luggage.
The main thing missing here is the overarching structure: when and how does the player's performance get evaluated? Should gameplay be divided into days? Should there be any way to extend the player's shift (or, by making errors, to shorten it)?
