This was a really cool experience! I wasn't expecting to be so freaked out, but often times I got a little jump when I'd turn slightly and see something right in my face :O. I highly encourage you to keep experimenting with the idea and make more enemies and areas to play in because its a very novel experience to play through :). One suggestion if you do continue working on it, try to make some enemies feel more novel based on their AI. So all the enemies you have move straight towards the player which makes one strategy dominant, but if for example, you add an enemy that tries to move away from the side that can see them or something (like trying to sneak up on you) it could change up what strategies the player can use, forcing them to adapt to new situations :o.
Overall, very cool, would love to see more! Also I really love the robot eye shader!
