I recently updated the game to have volume control. as well as remixing the noise channel down an octave. (some had more than one)
I also added a pause screen which allows you to change the settings above as well as view Peryil's status and view a map of the level
in the volume control I also added the ability to switch between the jam version of the music and the new remixed version.
I also facepalmed on one of the level music I had accidentally left one instrument channel completely muted in the jam version. (Level 3's theme. wave channel)
