Space to Shoot when you have the ball. Down Arrow Key is what I added. You can now turn around. Left and Right Keys to turn. Up Arrow Key to move forward.
@acustalow I added the ability to turn around but I couldn't figure out how to replicate the way the ball shoots while turned around, so I just set it to 90 degree shot when that way. You can still turn the normal way and shoot exactly as before too.
