That’s a good thought.
I think for this game though, the mechanic might get lost in a first-person perspective since you’d be completely blind to where you’re moving. With it being top-down you can at least still see the layout of the room since the walls are not culled. However, it would be much more immersive and I like the idea of using spatial sounds to tell the player where the enemies are located. So maybe it would work.
Anyway, thanks for playing!
