Really solid base for a game. I can tell you've put a lot of effort into this. I particularly enjoyed the blinking animations: weapon reloads, and the plane flying in the background of the intro. all very nice. The camera sway didn't feel great. I'd prefer the sway only be applied to the weapon or crosshair and not the entire camera view. Hmm..I didn't notice it until later in the game though so I wonder if it may have been a bug after sprinting? Perhaps it didn't reset to 'idle' afterwards. idk.
Do you have any plans to sell any of the assets? fps animations/character rigs? maybe on itch.io or unity store? there are not many options for this style of art at the moment. it might be popular
either way thanks for sharing! cant wait to see more
