I've recently have been told by a few people that my webcomic, Space Pack, has a feeling more akin to the Slice of Life genre than the Sci-fi it's listed under. I honestly somewhat agree, and am considering whether or not to change its genre.
But that's where my question comes in! Can Slice of Life comics have an overarching plot? For example, in my webcomic, there's an overarching plot involving aliens that will eventually lead to some moments of action, some drama, and ultimately, a conclusion. Even with that, though, the comic very light hearted, it follows the teenage cast often going through normal life in the suburbs while getting into some unusual situations along the way with some alien nonsense.
Does this sound like it could fit the genre, and could it maybe appeal more to readers of slice of life stories than sci fi? I would love to hear your thoughts, I'd really appreciate it!!
Thank you so much in advance!
