Neat game! The different types of power plants were really creative, especially the roulette wheel. Having multiple of those in the building is really chaotic in a fun way. I could definitely see a fleshed out version of this game with more types of plants and goals to achieve being really engaging.
The only problem I had was I felt it wasn't very clear how to begin earning money, took a second to figure out I had to grab and let go of the wheel to spin it. Other than that though great job with this!
