Okay
i actually did kind've like the graphics and how the style of the enemies and the different types. I believe this could be good and i would enjoy playing it.
-Make the gun a more life-like, with recoil, a better sound and maybe reloads.
-Some of the larger enemies should have more life, and what would could make it really nice is big big bosses with different attacks and differnets hit-points and such. Good luck with your game.
