This is a amazing idea for implement the topic of the jam. I love the art style , it is very unique and stands out from other games.
In the beginning i just killed everything that stood in my way and i got the worst possible ending. Then i realized that i don't have to kill anything and that i have to be killed to get progress. That was awesome, especially because the world is much bigger than in my first run.
All in all this game is awesome, i had so much fun playing your game. Great work!
