I have a few ideas. First of all great job. This shit dummy fun. Okay first idea. Add multiple color options for the crosshair in the menu. Its not a big deal to some people but I have a friend thats colorblind, so it really helps some players. Second, instead of making the enemies perfectly accurate, have them aim for a single point in center mass of the player, and down the accuracy just enough so that they still hit all their shots when standing still, but it wont be hitting the same point on the body every time. This just adds a little bit of immersion. Also this isnt the most important but a small story or some objectives would really improve the fun.
