For a Uni assignment we were told to make a game of our own choosing. We quickly decided we wanted to make something gritty and grimy, preferably set in one of the two World Wars. We eventually settled on the Siege of Leningrad. I was responsible for pretty much all the level design and the custom architecture tilekit.
The game lets you play as a young boy who amidst the ruins of a bombed out bar finds a bunny which he follows from his school throughout a street to his home on the other end of the street.

This lovely car I found on Sketchfab was produced historically somewhere in 1936, so a perfect fit.
