After you get a certain amount of souls the chicks and chickens will all respawn and the difficulty ramps. It's basically just a highscore game without any actual highscore system tbh. Highest I've seen was 160ish.
I was only able to have one person even playtest the game before submission and it was on my own PC so I was unaware of the audio issues everybody mentions. Hopefully I'll be able to have more playtesters on my next project. Appreciate the feedback!
