Helloooo! Thank you so much! This is so good to hear and honestly means a lot to me. ๐
Everyone should be able to make the game their love without spending countless days working on the basics. You mentioned that you're a Map designer, this is literally a major aspect of what makes a game unique and so much fun, and it already takes huge time by itself.
Again I appreciate these kinds words, and will do my best to keep updating URST to make it more advanced and suitable for the majority of designers and coders as well.
Your suggestion is already on my list, a simple "Can Hear" checkbox to let the enemy be able to hear the player footsteps and gunshots. It's a must for game with stealth levels ๐
