Now power plants like coal and nuclear have sliders to control energy output more precisely, though due to their high reaction time, it takes a while for them to adjust the power. The next thing I added was a money system that gives the player income based on power delivery and grid stability. While testing, I noticed I sometimes couldn’t buy a plant, and after digging into it, I found out that the shop button and the buy plant button could overlap, triggering both at once and causing a freeze.
