This colorful Dimahoo interview originally appeared in the Great Mahou Daisakusen OST liner notes. It features commentary from programmer Yuichi Toyama and designer Kenichi Yokoo, as well as composers Kenichi Koyano and Atsuhiro Motoyama. Toyama shares a number of fascinating ideas that ended up getting axed, while the composers talk about their general approach to the music and various technical challenges.
