such a bright and dynamic! i love your use of lietmotifs and variations when moving through different areas of your game. adaptive OSTs are always a favorite of mine, because it gives each location so much personality and makes the game feel more interwoven. you've achieved that well.
i also like your musical attention to detail. your switch between modes to represent different worlds is really creative and not something i would have thought of.
overall, great job!! keep it up!
