For being made for a gamejam, this was not too shabby! Quite a solid little game. Quite fun and reminded of the early doom games. Made a video on it.
Thank you! It was my first time ever doing a jam so it makes me really happy to see the game continue to be enjoyed by others even after the jam ended! To answer the question about difficulty scaling, each time a warning popped up it would spawn another angel. As for their AI its dirt simple, as they just randomly roam in a radius centered on the player. I've definitely improved enemy scripting since then, but nonetheless I'm glad you enjoyed the game! :D
