-Touhou Bomberman/Detonate on Sound (best party game ever and several times more hilarious than any actual bomberman title)
-Megamari (classic megaman on steroids... except with Touhou characters)
...as well as a few others.
But I still love the bullet hell titles, "Perfect Cherry Blossom" and "Subterranean Animism" being my overall favourites in the series.
