Thank you for starting off so strong; the game has huge potential. I do understand you wanting it be a more stealth like movement. I could really only think of those two ideas though.
Maybe for the NPC line of sight thing: What do you think about having a stealth/focus button (like the last of us) in place of the crouch button (that is, if you aren’t planning to add crouching)?
Also its all the guys that watch across the street. Maybe I should just run a loop before I start taking pics, but I regularly come out of the old mans shop and try to no scope a shot and WHAM eagle eyes (both on the left and the bottom sides) starts shaming me.
Will definitely be keeping up with updates though. In my opinion, it’s already one on the better non VN r18 games on itch.
