Making The Player Shot Fire on Angles
Once you make this change, you'll have to add a few parameters for the basic bullets to make them fire straight up. In this case, the xSpeed is zero and the ySpeed is -8.
✓ Test your program - it should work exactly as it did before.
Adding More Bullets
✓ Test your program - are you now firing 4 total shots? Are some at an angle? Before moving on, turn multishot off and make sure that it reverts back to normal behavior.
✓ Can the user purchase multishot? Is it possible to accidentally buy it more than once?
