This is great for a prototype! I think it is a bit too fast at the moment, but that could just be me. I also think some of the mechanics are a bit finicky. Maybe make the map bigger and have the fire spread and kill the monkeys slower, I think that would make the player "panic" still, but not make everything happen too fast. If I'm not wrong, some of the levels were not even solvable. I also think you should find a way to further focus on the climate change aspect and changing the story, or maybe this could be done by simply giving a summary of what is happening in the Pantanal and why.
