- SquareRaid is a lunar lander type game... except instead of a lander, you're a square, and instead of landing, you're mercilessly carpet-bombing evil enemy squares, and instead of taking place on the moon, it's on earth. Other than that: exactly the same. Controls are W/A/D for up/left/right and B for bomb. Score appears in the upper left, screen wraps in all directions, enemy squares spawn faster as you progress. Also... they will fight back!... (UPDATE: fixed score not displaying by putting it directly on the canvas instead)
