This seems to be a great concept, both in keeping with the jam theme, climate issues, and as a compelling game that lots of people would want to play. The idea of mini-games is brilliant and would work great in the overall concept of planet Earth and climate change. There is not a lot of info currently on what those mini-games would consist of, but I look forward to seeing more as the production moves forward. It does seem like a big project for a jam, so maybe consider just a minimal number of mini-games so as not to get overwhelmed. I also think balancing the fun factor with climate catastrophe could be difficult; I hope you find a good way to do that.
