You know, this is a really good idea and I wish I could have had it in there, too.
I feel really strongly about how much music can influence how you feel when interacting with any media, and I wanted to write the music to follow the flow of the game. I adjusted the spawn rate of the ads based on what was going on in the song. If the level continued past 3 minutes, even potentially endlessly, I don't know if I could have written music well enough to account for that, ya know?
I guess its a trade off? lol Thank you for the feedback!
