Update 5 (end of Day 4):
- Added 5 new structures: Housing Complex, Entertainment Complex, Greenhouse, Water Plant, Mining Rig!
- Citizens are a new 'resource' though not yet fully integrated (since no structures can produce them)
- Various changes to the Resource Manager to allow Food and Water control
- Camera swivelling, rotation and pan clamping
- Various bug and issue fixes
The following days will likely be less exciting as I've got lots of mostly coding to do to get future systems to work!
