Press arrows to move the ship. Press space to shoot your own bullets. Every time you defeat the monster, the ring will turn invincible. Every level you pass, the monster shoots out more bullets and bombs and adds another defensive ring around it. There are 5 levels. Have fun! NO ADVERTISING!!!!!!!!!!!!!!
Thanks to udemy, I watched a video and learned how to program this game. Thanks to one of my classmates for the gun upgrade.
