ASTRO BUSTER

The object of the game is to clear lines and score points.

The Pieces (astro-objects):
There are several different shapes, each made of squares. They fall from the top of the screen one by one.

Movement & Rotation:
As the pieces fall, you can move them left or right, or rotate them to fit into empty spaces.

Clearing Lines:
When you fill an entire horizontal row (10 blocks wide) with no gaps, that line disappears, and you earn points.

Increasing Difficulty:
As you get certain points, the game speed increases and the pieces fall faster periodically.

Game Over:
The game ends if the blocks stack up to the very top of the screen and no more pieces can enter the field.
