My first ever build in the demo was just a platform path off of the sink head in the kitchen and a small vehicle spawn area on top of the light.
Naturally, I experimented with all the features, so I built a bunch of light blocks around the kitchen, and spawned all the weapons at the end of my bridge.
FYI: I tried to make my character look as much like it did when I built this as possible. Oh what a noob i was.
