I really like the idea to this, the feeling of opening a door and knowing nothing was nice and the mechanical nature of the opponent with it scanning in red was scary as it lights you up with a red spot.
However it would be in the ceiling sometimes and I am not sure if this is intended but it looks like it goes through objects when it spots you which felt unfair, also when opening and closing doors to escape it you can often get caught on them which can be aggravating.
I am not sure if the view distance is limited for performance or gameplay reasons but it feels off when the opponent can scan you from a huge distance when you cannot see the other scans it has at the source but this also gives a sense of unbalanced-ness
Finally it says LShift to sprint but I never noticed a difference between using it or not.
I hope this does not sound negative or hateful, I really liked the game and dread it makes you feel when you get pinged and would love to see more updates to the QOL aspects :)
