My game is nearly finished (will keep tweaking it) and after a talk with Rich and Dai, I've decide to do another short project to learn Unity with Rich Morgan. This will consist of a environment that can be walked around and look good.
We've decided to base the level on the South Bronx in the 70s/80s.
Here's a work in progress of a tower block I'm working on. I'll be adding some more detail and texturing it soon.
