I didn't understand anything really. Would be cool if you made the game simpler and not having to change guns and enemies having numbers on them and i shoot them and sometimes they die sometimes they dont
I agree that the game can defiantly use a better tutorial. The numbers on enemies are their health, which may be negative in which case you need a gun that deals negative damage because guns that deal positive damage only heal them. The opposite is true for enemies which have more than 0 life.
