Is there a way to restart a game that isn't lost yet? R doesn't work as it selects the reactor.
Also I wish the water-rise levels were more realistic. The water level rises like 400+ meters in your game, while in reality the maximum possible rise (if literally all glaciers and ice caps were to melt) would be 70 meters.
It just feels weird as you address a real life problem, but then the proportion is wrong by a ridiculous factor. The expected sea rise over the next 100 years is often stated as 0.3 meters. And you have 400 meters rise in like 50 years. That's wrong by a factor of 2666. It's so absurd that it defeats the point of your message. If you apply the same error to e.g. height of humans, then the average person would be more than 5 times as big as the Burj Khalifa. Far, far, far away from "totally realistic".
Maybe you should add some intro to your game which points out that it's some fantasy or scifi setting with very wacky physics.
