Tank Hero "Only One bullet!"

this is my first GMTK GAME JAM sadly i had a lot of work at those 48 hours but i managed to make a game so the game is about a hero how operates a tank and he has to survive an evil army of tanks but he has one bullet but it's special if you fire it it doesn't vanish it appears to your left and you have to take it to fire again hope you like it thanks <3
