Made for teaching Scratch at the Onna-son Children School of Science in Okinawa. The teaching plan is to let kids reproduce the basic code found in https://scratch.mit.edu/projects/118723464 then show them a bunch of modifications (score, sounds, win animations, weapons...) like in this project they could do without giving them the code and then let them add the features they like. Has been tested in a 2-hour introduction to Scratch to middle-schooler and found very effective. Explosion sprite from https://scratch.mit.edu/projects/900513/
