Very coool game! Love it. I think you did some nice things with transparancy. It is missing BG music though, so definitly something you should add in the next version.
Thanks! Regarding the music, if you press X or Y you turn on the diskman and choose between 6 songs. But these are just examples, composer Edmo Caldas is creating the game's soundtrack and in order not to copy them, we agreed not to make them available in the DEMO game.
