Aww, tootache is awful - I have some teeth issues at the moment too.
Funny thing about what you said - I actually NEVER noticed Rama's route has no kiss scenes (and god knows how many times I've played the game) until the Steam version. And I wouldn't have noticed either if it wasn't for the trophies - since you put trophies for the kissing scenes, so obviously he doesn't have one. I tend to notice stuff like that, so it means I think the route is very satisfactory without a kiss scene. I dunno, I liked it just the way it was. But then again, this is the most satisfactory route ever to me, so yeah, I guess some people may be bothered by that?
OOC choices may be a very cool thing, actually, as long as the character thinks to him/herself something like "I don't really know why I did that". Heart no Kuni no Alice makes an interesting use of that. While romance choices heavily depend on the character you're romancing, you also have a hidden "sense of responsibility" stat. That's basically Alice's urge to go back on Earth and finish what she had to do there, go back to her life and put it straight and things like that. A bit like Tamara's thoughts about her having to deal with her uncle and stuff. Since at the beginning Alice wants to go back, the in-character choices are those that add sense of responsibility points. But if at the end of the game you have more than 3, she'll feel like she must go back on Earth which basically grants you the bad ending for any route you're currently playing. For her to stay in Wonderland and get her happy ending with your chosen bachelor, you have to go a bit OOC on responsibilty choices.
