Final Project:

for the final project I decided to make a alien invading game I ran into a lot of problems with the arrays and then I decided to add a boss fight if you defeat all the previous aliens but for some reason the shots that the boss shoots doesn't work when it hits the spaceShip we'll its a tank but my variables its called spaceShip otherwise everything works fine. Sometimes in the alien moving they go really close to each other I also made it so that if a certain amount of aliens are killed the others shoot faster same with the boss and his health. Another thing I noticed which I don't know how to fix is the game itself is really slow when most of the aliens are on screen but I thinks thats due to how I drew them.
