Vanish

The red force and the blue force each own sixteen raised blocks, four rows by four columns. They take turns firing a star from a launcher at the top: the attacker secretly picks a row and a column on the other field, and the star flies at that block, growing as it falls. The defender moves a round force shield in the sky above its own field to stop it. A star that gets through makes its block vanish, and the attacker fires again; a star stopped by the shield, or one that falls through an empty square, ends the turn. The launcher moves along the top each turn, three star speeds and three shield sizes set the challenge, and the side that loses 15 blocks loses. Play a friend or the computer.

Controls: Joystick and side buttons. To aim, hold a direction and press a button (up 1, right 2, down 3, left 4; the button alone repeats your last choice), first the row, then the column. To defend, move the shield with the stick. Red uses controller 1 and blue controller 2; in one-player mode, either. On the title, up and down choose a line, left and right (or a button) change it, and a button on START or CREDITS selects.
