Hello! Thank you so much for testing my game. I realized that I made some mistakes with my ammo system during the final hours of the jam, haha. Adding sockets to carry guns and ammo is a great idea which I will definitely try.
You're absolutely right! The issue of enemies shooting through doors was quite strange, and although I managed to partially address it by setting up different collision layers, it's not completely fixed yet. The enemy system as a whole was one of the most challenging aspects, but I learned a lot from it. :)
