Nebulasray/Gameplay

Controls

 * Joystick: Use the 8-way joystick to direct your Fighting Rays around the screen; they are always moving forward, but you can direct them anywhere.
 * Firing Button: Use this button to make your Fighting Ray fire shots at the enemies; you have to press this every time you want to fire a shot at them.
 * Bomb Button: Use this button to make your Fighting Ray launch a bomb at the enemies; if it doesn't have any bombs, this button will have no effect.
 * 1 or 2 Player Buttons: Push these buttons to begin the game as player 1 (red), or player 2 (blue); if only one player was present, it will say the other player score was 7650 (Namco's goroawase number) on game-over, and it will also say that both players' scores were that value in the attract mode.

Fighting Rays
These two ships are the protagonists of the game; Player 1 controls the red one on the left, while Player 2 controls the blue one on the right. Unless they are shielded, they will lose one life whenever they take a hit from an enemy (or anything that is fired at them by one).

Capsules
When one of these is destroyed it shall leave a powerup behind; there are nine different types of powerups and all but one of them have a letter on them to indicate what they do. Three of them can be collected until their letters change to the word "FULL" (but will wear off if you are killed), while four of the others shall cause a counter that starts at 999 but decreases very quickly to appear under your score (and will wear off once it reaches 000, or if you are killed while it is decreasing), the eighth one grants you a bomb (up to a maximum of eight), and the ninth one (which is the only one in the game to not have a letter upon it, but if it did have, it would likely be "P") only seems to be worth extra points.

Capsules are also enemies, and shall attack by firing pink lasers at the Fighting Rays (which will, just like a hit from everything else, kill them on impact); they are also worth 1000 points when destroyed, and the Point powerups are worth 3000 points when collected (indicated by text "3000 Pts." on screen).

Bosses
STAGE 1: Uchu Kukan - Once you have fired off enough shots at the cockpit of the last Enormous Battleship for the stage to destroy it, this enormous ship (which had been attached to the back of it) will take off as the first boss battle of the game begins; the eight bombs upon its bottom section will revolve in a clockwise direction while firing eight spreading pink lasers at you, so it is advisable to aim for these first (and these are all worth 500 points when destroyed). However, if you take too long over destroying these, they shall eventually launch themselves at you - and if you cannot fire enough shots at them to destroy them before they hit you, you will have to move out of their way. Once you have destroyed all eight of the bombs (or they have been launched, off the bottom of the screen), it will start firing blue beams at you from its four side-mounted laser cannons - and you can either aim at them (as they are all worth 1000 points when destroyed) or its now-revealed core (which had been hidden by the bombs at the start of the battle, but if you choose to destroy all four of the cannons, you will have to aim for it anyway) next. Once you have fired enough shots at the core to destroy it, the entire ship will explode, as it falls off the bottom of the screen (however, you will not receive the points for any of the laser cannons you did not destroy) and you will receive 20000 points; the screen shall then fade out, and you will receive 10000 points for every bomb you have, and 30000 points for every Point powerup you collected during the stage. You'll then proceed onward to Stage 2.
