I love that you made this! The whole "we only have one planet" sort of concept was something my team joked around with when we were initially coming up with concepts, and it's so fun to see that someone made it come true! I'm glad you were able to put out this project even after a rocky start.
I actually found the game very relaxing, it's perfect for some after jam winding down! :) The pollution mechanic gives a nice sense of urgency, and it's cool that you have to think about the building placements for the combos. It's also a nice touch how the planet's smiley changes based on the pollution!
