"... but one day it will spin without us." -me, right now
I like the game concepts, and how they show blatantly damaging things alongside more everyday actions (like drilling oil, to driving). Not everything bad for the climate will be as obvious and easy to cut back on or ban, many of them are integral to modern society, that's a really good message. The theming seems pretty good, but it seems like, realistically, you should be trying to fail the minigames, or you're just an observer of humanity and the gameplay is just for the player's entertainment.
The fact that when you lose it lets you try the minigame again makes it seem like it might play as a scripted campaign; playing each minigame once until you've done them all (there's also an argument to be made that that itself is a message, like that no matter what, you have to pour that toxic waste into the water), which is something that other warioware style microgame playlists never seem to do, so it's an interesting approach (assuming that's the plan). Even if so, I'd recommend some form of random endless mode. The scope is based entirely on modular microgames, so when push comes to shove, I can't imagine it being too short on time and releasing in a noticeably unfinished state, you just might have to scrap some games.
As for commentary on the prototype, I'd recommend removing the "!" after the time, but that's about it. It seems like the framework is there, and all you need is the games, and art.
This is a good concept, with pretty good impact and theming. Nice work!
