Little Busters! is my favorite Key Visual Novel to date, a fact that remains secure after having just finished Rewrite, their newest release (spoilers for the upcoming review >.>). Little Jumper plays in the final end credits for the VN and at the time I felt that it fit the mood I was in perfectly – I would go so far as to recommend Little Busters! just for that end feeling (though the rest of it is good too!).
