Thank you for your feedback!
I see how that can be confusing, the problem is probably that you played without headphones, because the 3d sound is VERY important to detect enemies and where they are, and not only that, you can also hear their "alertness level", and if they get too angry you should stay quiet until they calm down. Thats definetly my bad for not making that more obvious, so your criticism is totaly valid!
Thank you for playing!
