Hey man, I just tried it out again and it already feels a hundred times better! I'm really glad that I could help a little bit. The game feels much more immersive with these new sound effects implemented and now it isn't unbearably frustrating to fight enemies. Although now there aren't that many and the game is a little too easy, you could spawn a few more enemies. Otherwise, it's a huge advancement so congrats man^^
