GO ON FULL SCREEN!!!!!!!!!!!!!!!!(please)!!!!! Then press the green flag and play the game.
Thanks to @djpro for a tuturial on how to do it. Also thanks to @dispicabememan for how to do the fireing in the boss battle. All the artwork is done by me. Someone pointed out that the game was broken. I think I've solved the problem, but if you see anything else feel free to tell me in the comments.
