I hate to leave such a low star review but there isn't much content, and a few aspects of the game don't really work right. Bullets don't keep going and stop moving at your crosshair, also enemies don't hurt the player or stop the game.
However! The art is nice, I hope you can work on it more and make it more functional! Keep working and improving it and I'm sure it'll be really good!
