Regarding this game's canon ending for the sequel IIRC I read somewhere here/ or maybe from the game that the pure married route is the canon ending and other endings are "other sides of the fem protag, but not exactly the same one as the protag of other routes" So something like multiverse but not really (there is no multiverse concept in lore, but the other routes work like different "multiverse/timeline" or some shit). Since that (pure married ending) is the only ending (not sure) that leads to the zombie apocalypse scenario (and the husband dying/zombified). I know that other routes also hints that the zombie shit is happening in the background and you get more of the lore if you play all the routes but the sequel has to follow one specific timeline right? So one route is canon while the other are alternate reality stuff that never happened in canon (since routes here are exclusive of one another). So will the protag of this game (forgot her name lol is it alansya) appear in the sequel as a side character?
A slice of life game? So it's pure love/ Vanilla/ harem game? Kind of a big switch in genre lol from what they are known for (granted it's not their main game but it can alienate their current fanbase due to the genre switch but can gain them new ones who most likely will not be interested in their other games due to the difference in the intensity of kinks).
