oh there's like a glitch where if you move to a screen with different music that fades in and then immediately go back, both of the tracks play at the volume they were at while fading out/in
it's like frame-perfect though so it's near impossible to do accidentally, you gotta like, intentionally scoot over one pixel before the screen transition and immediately double back so i wouldn't worry too much about
i like how the hearts have names now, makes it easier to say like which one you just got
