I used max mouse sensitivity and it is still too slow for my preferences (slower than in other FPS games I played).
I hope it would be easy update to increase mouse sensitivity range to noticeably improve comfort of aiming and reaction time.
I saw many negative reviews and maybe current state of the game should be released in early access to avoid such unpleasant situation.
Personally, I very like concept of this game and see potential in it.
Gameplay needs some tweaks, but is not as bad as for indie fps game made by small team with low budget.
AI is not perfect (it is not in other, even AAA games), but impressive, because I know it might be one of hardest things to code well.
Graphics are not as bad when compared to other small games (or even Fortnite) and girls are very nicely done.
I played a lot FPS games (SWAT 4 is one of my favorites - I see inspiration) in last 20 years, including indie ones, and this game is still interesting enough and fun to play for me.
I hope you will not give up due to some unsatisfied gamers and will continue with updating your good work.
Just remember that there are still people who like it.
