The font is very, very hard to read. Otherwise - I'm getting mixed signals from the game. On one side - it seems like you're going for realism in the gunplay, on another side - there's flashy movement. It's interesting, and both of them work, though I'm not sure how well they mesh together.
Not sure about the default keybinds, alt isn't the best key for something that you're gonna use ofter. Rebound it to my mouse and it worked perfectly, and felt pretty fun.
The gunplay is fun, but TTK is very, very low. Is it intentional? I started camping with the mosin nagant looking rifle, worked pretty well, but that wouldn't let me experience the flashy movement. At the same time using all the fancy moves that you have gets you killed pretty fast.
Anyway - it seems interesting. I'm curious about what you're gonna do with the systems that you have here.
