I think keeping the modes matched to the song that plays during that scene in movies is a good idea.
On our own would be a great multiball song as previously mentioned especially if it is a longer edit of the song than is currently in we got one (custom code edit).
Higher and higher would be cool for high score entry if possible.
Spooked librarian is good but needs higher volume and game start couldnuse slightly higher volume.
Haven’t gotten past gozer mode so i have no idea what songs are already in game during those modes or the song for last mode on left ramp and wizard modes.
This collaboration definitely adds to an already great game, tripled my previous high score on second game after update. More immersive GB experience!
