Hi thanks for the comment. Adding to what you already noted, I had many other ideas that I had to scrap due to time constraints. I had wanted to include buildings in the city. There would be were missions to fly to different parts of the city. You could bring a group of scientists to the volcano to study it, thereby increasing your time available. Perhaps there would be a hospital that you could land on top of and drop off wounded people for medical care. I also had the idea that the lava balls could cause fires in the city that you'd have to put out with water. By the submission time, I was just happy I had something to submit. lol
