I think this jam idea is really cool! I also really care about the planet. I hope I can make something in the time, but since I am flooded with deadlines and need a long time to make a game (I work in Unity), I am not sure.
I'm sorry, but though I got a good start, I am nowhere near done with my game. Maybe if you do something like this in the future again, I can finish it. But I do not want to publish an unfinished project (that doesn't even have the main game elements in it!). I love the concept though, thanks for having this jam <3
