instructions in game, but here they are: arrow keys to move, space to shoot. press [M] at any time to access the main menu for upgrading.
i have added menu, upgrades, better AI, shooting enemy, money, tm colours (dark red, light red), a logo (the pixel circle that says S.O.S on it (S.O.S stands for Shoot-Out Showdown)), and realignment to the original game the back-up upgrade will shoot at the enemy and destroy it, but it WILL NOT block the lasers
