I have mentioned trading Chris for Kane would be wonderful. As an Aussie, i like Chris, but, damn he can be annoying, kind of glad no route is being discussed. Sorry if my opinion does not fit with others.
that brings about my second thought. Being a game with romance options, sometimes you will hear from players who do not vibe with any of the characters. that is not a fault of yours mate, but just part of being a creative artist. Not everyone will accept what you create. sometimes for valid reasons that you can control. but you cannot create a romance that will fit everyone, and that is not a weight you should carry. IMHO, what you have so far is really good. Very fun characters that are not carbon copies of each other. Different tastes, hobbies, dreams, enough differences to make different routes worthwhile.
Ooh did i mention, that I am team Kane :p
