does it have to be your death that is progress or some enemy's

well usually in a game jam the player can twist the theme however their liking, as long as it fits the theme, you can make it whatever you want ;)

Thanks BrickLikesCoding! Yes, as said you can change it a lot, you can even use the term of "Failing = Progress" instead of "Death = Progress".

It's totally up to you how you show it to the people!
