go over how to make a list of lasers off the screen
then make them show up and move when you press the 'A' button
the PyBadge have 5 NeoPixels
you can use RGB values to set them to any color
255 is really, really bright; seriously I use only up to 10!!
since you have 5 lasers, set each NeoPixel to green when you can shoot it and yellow once it is shot, then set all 5 to red when you have none left!
this will really help
you will need to load the lib directory with the NeoPixel library onto the PyBadge
