BRICK[bricksmash]SMASH is a game about recursion by Alan Hazelden.
Why Try It: A cute, recursive take on Breakout and similar games.
Author’s Notes: "BRICK[bricksmash]SMASH is bricksmash inside BRICKSMASH."
From the forest ambassador: Losing a ball inside one of the bricks doesn’t cost you anything, but if you lose your main ball and still have an inner brick game going, you can finish it to transform the brick into a new ball.
