1, 2, and 3 were well deserved, but there were a lot of really good entries in this jam. I don't think the last jam had nearly as many games. I was pretty happy to see myself in the top 5. I wasn't sure if the game would run well on the judges' computers, since I had no time to optimize the rendering code.
Undying City is a neat game. I don't see why someone is stuck on labeling it a Unity 3D game. In some ways, it looks similar to Nikkita31's Infiltration (particularly with the way walking behind buildings is handled), but in an isometric perspective.
