Great concept and great execution! I'm surprised that y'all made every asset from scratch, but I guess that's the benefit of having all art school students ;)
The gameplay tutorial video helped a lot, but I feel like I would have been very confused if not for the video.
The idea of playing god on a simulated earth and doing Among Us-style minigames is fascinating, and the integration of different terminology and research like Ozone levels is great! Although I felt like adjusting water and core temperature levels directly was a little too Sci Fi-ey for my liking and would have liked a slightly more realistic approach (ex: melting/freezing glaciers maybe? Or adjusting clouds/rains for temperature) but I do understand that there are affordance issues vs a more direct approach.
The PS1 dithering shader and lowpoly assets really shine, though I felt like some textures felt a bit too high-poly/high def and stood out from the rest. A minor issue though, given the sheer number of assets!
Overall, amazing job yall! <3
