The music stops, when you fail. Overall, I really liked the concept, I've never played Ace Combat, but I was reminded of Airfix Dogfighter, which I used to play a lot as a child. So this game felt nostalgic to me. Also, I'm impressed by the amount of work done in only three days, this is a very solid one for the jam.
My only problem is the prep screen, it's fiddly, and the sliders kind of don't indicate, why they jump from place to place. Also, I would love some indication, that W increases speed (maybe, add a sound engine, which revves up with the speed). But outside of those nitpicks, and incredibly well made jam game.
