Your game remind me hotline miami immediatly, it works well but its hard ! Probably because character are too big on the screen and camera not see far, and ennemy fire shoot is quick. In hotline miami you can press shift for example to push the camera and see in looking direction. Correct this point and the experience will be better i think ! There is also small collisions problems (like throw weapon on wall and when you turn character near a wall for example) but its was just details. Good job !
