Pico Invaders for #Pico1k

My first entry into PICO-1K games Jam ( https://itch.io/jam/pico-1k-2022 )

This is a full on "hard" mode version of the jam, the entire game is contained within source code that is 1024 characters long, all graphics and sound are contained in the code.

It's a fairly basic space invaders clone.  The one twist is that every shot you take costs you a point from your score.  So spam bullets at your peril!
