Thanks for checking out the demo and for the feedback!
Flashlight would be awesome but will be tricky to pull off with the way we have set up the environmental lighting (vertex colors). I have an idea of how to do it though, we'll put that on the list of potential features for sure.
Ai is indeed rough but fear not, it's getting a massive overhaul for the final game. Same goes for the player gunplay, and most of the systems in the game tbh.
Enemies being invincible when being hit is a new one, we'll look into that.
As for the port-a-johns... The deep state spares no expense, proper hygiene is critical on a black site!
Really glad you liked the demo, thanks again.
