Space Invaders crossed with Pang crossed with Robotron. Trying to target a Pi Zero because optimisation is fun.
Left and right arrow keys to move, 'Ctrl' to shoot. 'Space' to smart bomb, one per game, refreshed every 4 levels. Press 'M' to mute music, 'P' to pause.
Needs: libsdl2-net libsdl2-image libsdl2-ttf libsdl2-mixer
