Monster Boy and the Cursed Kingdom composer info

[JAMMAPARTS]

As a fan of this excellent game and of the music, as you may know the composers are some of the best of the best: Yuzo Koshiro, Motoi Sakuraba, Michiru Yamane, Keiki Kobayashi, and Takeshi Yanagawa, with the main theme performed by Haruka Shimotsuki.

Any idea of a composer list for the tracks? I have my guesses, like the main weapon shop theme maybe Koshiro and there is a sewer level that sounds very Castlevania-like so probably Yamane. Any ideas or guesses for who composed what? The soundtrack alone took them 2 years to make, well worth the cost of the game just for this collection of awesome music.
