Thanks. Much better now. One other problem though... when you die and start back at the top you can sometimes start and instantly get hit by a hammer which means you lose another life before you had a chance to do anything else. When you lose a life anything near the spawn zone should disappear or change direction so that you're not trapped.
Not a problem, but a possible improvement would be to be able to shoot up or down. It would make it a little easier to destroy things.
