Game of Life

A basic implementation of Conway's Game of Life in the PICO-8. Game of Life is a zero player game made up of cells that can be either alive (filled in) or dead (blank) and follow these rules:

• A living cell survives only if there are exactly two or three other cells next to it that are also alive.
• A dead cell comes alive if there are exactly three other cells next to it that are alive.

Controls:
Circle button (Z) - Start and stop the simulation.
Cross button (X) - Randomly generate a new starting configuration.
Left/right arrow keys - Change the initial population density (how many cells are alive at the start).
Up/down arrow keys - Change the simulation scale.
