The game is fun and cute. I do have to admit that with these types of waiting games I start using autoclickers to speed up the heating of the sun, especially because when you have a certain amount of meteors you simply have no radiation problem. So it does need a bit balacning.
It fits the theme perfectly. The audio is fine (bit low on my end). The gameplay is solid for what it is supposed to do. Art style is cute and fun, yet for some reason I wish the meteors were also cute.
Goodjob.
