The player controls Layla, who has to make her way through 8 asteroids to rescue her friend from the malevolent doctor. Along the way she must collect password disks in order to face the doctor's worst creation. Without them, all hope of winning is lost. On each asteroid the player will be required to make their way through a maze to collect the disk and face the boss monster. After each level there is a bonus stage where the goal is to shoot down every enemy formation that appears for bonus points.
The main game is a run-and-gun where the player traverses across each area shooting any enemies that gets in their way. There are non-lethal pit-traps (it simply places the player at the start of the room with some health loss). Each enemy in the game can be defeated by shooting them and once they do explode they will drop a sweet - these sugary items will restore your life. Should the player lose it all, it's game over as there are no extra lives in this game; the player can, however, use a password to continue their game. The bonus levels are pretty much a Gradius clone except it is impossible to die; It's simply a chance to get as many points as possible.
Layla has a vast arsenal of power-ups at her disposal for such an old game; where a game like Castlevania might limit its protagonist to his main whip and an additional sub-weapon, Layla actually allows the player to collect and stock up on various ammo types for when they're needed, which she can recover by destroying the crates she comes across. In perhaps this sense only, the game is a precursor to games like Doom - where keeping a large stock of different weaponry is a necessary tactic for survival.
Roller Skates: This makes Layla run faster.
Pistol: The default weapon. Infinite bullets.
Machine Gun: Fires quicker than the normal pistol but requires that the player pick up ammo for it.
Hand Grenade: It explodes after a few seconds of throwing it.
Flame Thrower: It burns enemies for high damage but it is only good at close range.
Ax: Layla throws this ax through the air pulverizing any enemies that might be above her.
Bazooka: Only really effective against certain enemies. Against everything else it is useless.
Light Sword: A slow weapon that will pass through enemies.
Shield: A shield that will protect Layla from all damage until its timer runs down.
Question Mark: Layla shall lose health after collecting this item, but one of four things will happen depending on where the cursor is positioned: Damage all enemies; destroy all boxes; earn 1000 points; or destroy all terrain.
Password Disk: A necessary item in order to beat the game. All eight are needed to defeat the final boss.
