Sounds very interesting. I had no idea mud volcanoes and LUSI existed so it's a great chance to educate others on the subject. Due to this, I would like to see a greater emphasis on the informative aspects of the real life LUSI.
My main issue are the asthetics presented can clash with one another as SimCity has a cartoony, lighthearted look while frostpunk has a realistic, hardcore look. One of these needs to be picked and I'd recommend the cartoony look to fit better within the jam time.
Can't wait to see the finished product
