A simple Snake game. Control it with the arrow keys, guide your snake to eat the red circles, and avoid running into your tail.
This code uses Cairo to create the images for the snake's body and tail.
A very simple particle system that spews white pixels from a central point that get pulled down by gravity and bounce on the floor.
A more complicated game. Control it with the arrow keys and hold the spacebar to fire.
The code also uses Cairo to render the player's spaceship and the enemy spaceships. In generating the starfields it shows how to render to a texture with SDL2.
Just draws random white and black pixels to a texture and displays it.
