Should have little-to-no music audio during gameplay. Focus on Walla (crowd noises) audio during scene-to-scene gameplay.

Title theme should be upbeat and slightly cheery. References below are from the Famicom Detective Club series, I highly recommend looking through the soundtrack and getting a grasp of its style. If you can make your own music for the game, that would be incredible, but it shouldn’t be a problem using free commercial use content if otherwise.
