The music is really nice! I also found the gameplay to be really engaging, the only that that would have really helped me is an idea of the towers' range, along with already unlocked towers not appearing as rewards
I was going to implement a tower range display on placing, but didn't get around to it, sadly. As for already unlocked towers appearing as rewards: Picking these lets you upgrade the towers to a new level! I probably should have changed the description for them in the upgrade menu, though...
