This is either a commentary on working conditions in parcel centers and debt, or I'm really bad at your game :)
Could be a bit easier :)
The PSX style aesthetics were cool, and the sound fit the gameplay. I noticed you have music in credits, but I didn't hear any?
There was one thing I'd change- it would be nice if the city names were sorta related to others in the country. For example San-Antonio being in a different country than Ivanovo :) Also- because of the style of graphics I had to get really close to read the map.
As for the usage of the theme- it was a pretty good one. The game kept you in one room (and not a nice one at that), and it affected the gameplay.
