I got a tip:
on aspect ratio wider than 16:9, put a left/right margin that shifts UI items to where they'd be if 16:9 in the center. here's an example so I think it kind of looks good with the wide view and the menu on the left aesthetically, but in actual usage the buttons are just too far and you have to turn your head so pulling them in to where the health is on the in game would be good maybe make their BG just a bar with the image in the background continuing past them to the left so it's like a sideways cross or something 
okay I can see that you've already got that for the in game ui
Now, something else that I've noticed is that you get messages while you are in combat or navigating the environment so of course you don't read them and its like just noise or a popup ad. then after when you're somewhere safe, you think "now what was it that they said". cp2077 solves this by having them codec call you and you get a notification icon. AT YOUR LEISURE (like, once the fight is over) press T to play the message. So I suggest something like that, OR to pause the game or start a bullet time or something, while a text box is on screen (like she a cyborg right? so she should be able to receive data faster than real time) and then resume normal speed when message is dismissed. Because I feel like now its as if the game is just made annoying by the calls you get because they compete an d conflict with what may be happening at the time in game play.
Also, when I last played it with default FOV it was kind of difficult due to how fast the gameplay was it was like star wars episode one pod racer the FPS. But at 110 fov it is fine. I would like that enemies are more lethal but die to fewer bullets cov when I'm running and side strafing at speed and I head shot them while moving, they should just drop. but they don't because 3 headshots doesn't kill even a basic enemy because they are too tanky, whereas I am imagining the game flow would be smoother if you could just rapidly run around and headshot but then you'd die if you were too slow. IDK just a thought but I feel like enemies tankieness slows down the gameplay where you kind of have to either waste a lot of ammo run strafing and shooting longer than their arc will be on screen at once so you shoot many past them too and kill them in multiple strokes, or even worse you just have to stand still and gun blast them for a sec to drop them then move again and its like slowing down the gameplay that I think would be better if it were faster paced. The spike attack is ace though against basic enemies.
It'd be cool if there were cyborg movement noises when you move like in blood dragon. like your a cyber commando or something but you make regular footsteps? disappointment. should make robocop footsteps.
Now, I know these can be controversial, but I would prefer hit markers, just little center-less X's in the same color as the rest of the UI. Maybe have an option to enable / disable. Also if enemies could rag doll with a physics force push on death that'd be cool (don't know if possible code wise though, but I imagine it'd make fraging more satisfying)
cool game, runs fast.
