I came up with a title for my game. I will be calling it "Get Rich Efficiently". Pretty boring, I know. In other news, lots of progress on the game was made today. I wrote a system for handling power grids, and added mines, which are powered off this grid. Solar panels were also added. They also got nerfed. A lot. The engine was also modified to add an inventory system and a day/night cycle (for the solar panels.) Here's a screenshot of what I've added today.
