I liked Harmony.
The music was great, although the quality wasn't.
The characters were pretty cool, I guess.
The castle, though... It's HUGE. nd it's extremely trippy, I mean, sheesh... I bet this game is a hippie gamer's best friend. It's like Juste was on LSD. What would've been weirder is if you saw Lucy in the sky with diamonds, or you fought walruses and eggmen.
So, the game was good, a bit trippy, and the music was good (What Castlevania game has EVER had bad music?) but with bad quality. I liked Harmony, and I'd give it an 8 out of 10.
