Yeah, I've got a bug with the death slomo, if you click the Main Menu button before the screen fades to black fully it stays for the next run. And you want to click it fast, because I've added a slomo and it takes too long .
I didn't want to update the game after the jam was over (not even sure if it's possible tbh), so I left it in, lesson learned: don't mess with slomo 15 minutes before submission!
