Well I haven't cleared any scenario yet but things are starting to get a bit more serious now, so I believe this would be a good time to write something about it.
Spoiler for Little Busters mild ones:
Well I haven't reached the baseball game yet but it's only a couple of days away now, I guess the things will really start to pick up after that. For now it's been mostly comedy with small hints of whats to come.
First of all I should say that pretty much all my expectations has been met and it's a pure pleasure to play it but it's quite different from older Key games.
As for the characters Rin is still my favorite just as she's been from the trail version but Yuiko (姉御!) and Haruka are very entertaining also. The only one that has disappointed me a bit is Komari, I'm having some trouble getting used to her voice but I guess it's only a matter of time.
The minigames are also quite addictive even tough I apparently stink at fighting
But Rin (with her cats) and Kudo (her dog managed to beat Haruka with one attack) can be quite terrifying at it.
