Little Busters - Initial impression

A few days ago, I got the Visual Novel 'Little Busters', one of the later work from Visual Novel developer 'Key'. I completed one the routes and while I am still playing the game, here are my initial impression. First of all, it is pretty long, it took me 14 hours just to complete 1 route. There are 5 or 6 more to go, as well as the 2nd part which is only available after you complete all these routes. There are several mini-games including the 'baseball' minigame and a fighting 'minigame'. After the first playthrough I am still struggling to fully understand the rules. For the story itself though, so far I felt a bit disappointed. All of the female characters appear to be overly 'moe', which is Japanese term meant to show 'cuteness', but it makes the characters appear a bit dumb. My favorite heroines in Clannaed were 'Kyou' and 'Tomoyo' because they were tough and independent. The only character who shows that sort of energy is he heroine named 'Kurugaya', but she appears plain weird in other ways. With that said, I did feel a bit interested in the main heroine 'Rin', after the first play through. (Apparently I can't get the full story right now). Also, I was expecting something emotional at the end, but nothing like that happened. The route ended abruptly, with a rather mysterious scene and no explanation. Either way, I'll continue playing, and see where it leads.
