I made a tower defense where every tower is an instrument, so your layout writes the song
Polyvale is a free browser tower defense. Every tower plays a note in a 16-step beat loop and only attacks when its note plays, so a good defense is also a good track.
Keep the mix balanced for +20% damage and to charge the Drop for double damage. Seven maps, each with its own song, a boss every tenth wave and a hardcore mode.

I'd love to hear where the difficulty breaks for you.
