# games/4s

This is a simple block stacking game, a port of Plan 9's games/4s
To play using the keyboard: as the blocks fall, the a, s, d, and f keys move the block left, rotate the block left, rotate the block right, anad move the block right, respectively. To drop a block, type the space key. You may need to click on the game window to focus the keyboard on it.
To play using the mouse: as the blocks fall, moving the mouse horizontally positions the block; left or right clicks rotate the block left or right. A middle click drops the block. (Unfortunately, some environments seem to intercept the middle click before it gets to Native Client.)
To pause the game, type z, p, or the escape key.
