Like you said, there are still things to improve. I find it really difficult to play this game. Firstly, I can't see the bullets I fire and how far the range of those bullets are. Secondly, but this could be a more personal issue, but it's difficult to rotate with Q and E, maybe integrate the mouse for the rotation? At last, maybe stop the growling of the zombies when you are dead, the loop is irritating. Nevertheless, it is great for your first game. This game has some potential!
