If I understood correctly there will be no poly routes, right?
Unless all character can be romanced at once, and we woukd have to deal with consequences such as they would be.
Well, according to (very old, so don't shoot me if I'm wrong) tumblr asks, you can flirt with ro's as long as you don't get locked into a 'route' beforehand- so, let's say I have a childhood crush on Nimue, but then flirt with Galahad, BUT I also sometimes flirt with Nimue as well. In game, it would probably translate to the two characters experiencing confusion regarding who I'm interested in, and potentially start a few arguments. (At least, from what I understood from, I'll say this again, very old tumblr asks.)
