I really like the game, and that could be an interesting idea!
I just think a few things could be changed:
-
The speed at which a “press and hold” action is detected could be faster (the current slowness makes it harder and uncomfortable to play, in my opinion).
-
Perhaps there could be safe zones based on the monsters’ hearing range (I don’t know, I think it could be a good addition); that way, one monster might head toward your location while another stays waiting in the same area.
