As you noted, this game sounds very educational, and I like the idea of focusing on a lesser-known impact, as many overlook lots of the effects of climate change. I think the format of the game would be great for younger ages, and smoothly introduce them to one of the biggest problems our planet faces. I also think focusing on the effect on an animal is smart, as many people feel emotional when seeing animals facing struggles, so this could use emotion to draw the player towards taking action.
