Very underrated manga about a snowy post-apocalyptic earth that's infested with kaijus. However, in this situation, the main character's top priority isn't to survive but to make friends like his deceased gundam partner wished for him to. This story can comfortably mix its depressing concept with fun and comedic moments while carrying an impressive and expressive art style. If you've read/watched Zom 100 and enjoyed it, it is similar in concept with both protagonists being put into these near-world-ending situations but striving to do very down-to-earth things (or at least somewhat achievable goals in Zom 100's case). The only thing that's lacking for Snowball Earth'scase is that (from where I'm at in the story at least) the action scenes are few and nothing special in terms of choreography, so if you're mainly looking for a new action series to get into, you shouldn't expect much from this. In short, it's an overall good read so far with a protagonist with a very understandable goal along with great art.
