I managed to beat the 3 stages, but i basically just ran through them. I tried to fight the enemies, but i couldn’t make out where exactly they are and never would hit them. My first thought about the turning via mouse was, that this is odd, but actually i think it kinda works. Just the mouse sensitivity is extremely high, i just do one flick and have a 360 degree turn, which is way too much.

The biggest problem here is, that the signal sound is way too loud and obtrusive. You used a plain square wave, which is very high energy and it’s permanently blasting at the player, without any variance or difference in volume. This is super exhausting for the ears, and it basically masks most of the other sounds in the environment, so you can’t hear the rest very well. Which is probably part of the reason why fighting the monsters felt quite impossible.

You could simply use a continuous beeping sound instead, which lets the player hear the other elements better, and is not that harsh, it really doesn’t need to be permanent, or you use a more pad like sound, that’s more pleasant to the ear.
