I can imagine that maybe there could be 1-2 more (Since at the end with all the character's silhouettes there were some i could't recognize)

But i also can imagine that the "main" routes are probably already enough and there should't be too many? Idk, every character has a story personality, etc, so probably having more routes would mean more work for you.

Yes, that is the thing - every single route is a lot of work. So first I need to complete the others. If there's any juice left in me, I might add more. Several of the silhouettes are really people that haven't been shown yet, but none are romanceable as of now.
