Right now, if you turn on game-sounds while alt-tabbed, you still can miss a few cutscenes ending, namely those without a boss "whoosh" sound.

Just have it so any time an unskippable one ends, we can know when alt-tabbed just having system sounds on with a simple beep.

There, new players can watch their cutscenes, and players who've done it before don't have their netflix/youtube/something cluttered with game sounds and don't miss when a cutscene ends.
