It's a fun concept and I like the idea a lot, it's just waaaay too easy at the moment. There's nothing stopping you from just waiting to get enough for a generator and then spamming them down in a small area since each generator just gives you more and more energy, and then spamming the lights and 10 houses you need once you have enough.
The presentation is also pretty rough but that's honestly normal for a game jam. The music was a neat fit though.
It's not a bad start, though! Definitely wish there was a more polished version that needed actual strategy, like more resources required than energy and placing limitations.
