Sorry for the belated reply! Thank you so much! ♥ We have thought about revisiting the existing routes to see how we can add more content but it's most likely that we would add a post-story episode for each rather than expanding the game itself out; we're pretty happy with the story flow that results from the short time window MC has in the existing story.
Thank you for the feedback though, it's heartening to hear that people want to spend more time with our boys, it's a sentiment we also share hahaha (esp Rye but don't tell anyone I said that... hahahha....)
Looking forward to releasing Briar's route as well :)
