Layla

Gameplay mainly involves controlling LayLa through the cavernous maze-like asteroids shooting at the enemies who get in her way.

Also of utmost importance is the collection of password disks that are found in each asteroid (they are needed in order to beat the game).

Each asteroid contains several elevators that take LayLa to the different areas of the asteroid she is currently in.

At the end of each asteroid is a boss monster that LayLa must defeat in order to leave the asteroid.

LayLa can find several items and weapons in each asteroid.

Weapons include things such things as handguns, machine guns, and hand grenades, while usable items include things such as roller skates and a barrier.

After completing each asteroid level there is a bonus stage involving LayLa flying in her ship on her way to the next asteroid.

The bonus stage is a horizontal side-scrolling shoot-'em-up that is viewed from the side.

Destroying an entire squadron of enemies will earn the player bonus points.

LayLa can't get hurt during this portion of the game.

Bonus rounds are only used to enable the player to increase their score.

Layla for Nintendo Entertainment System is currently worth €46.55 loose, €233.01 complete in box, and €745.56 factory sealed. Prices are based on real sales and update regularly on Gamevaro.

Layla has a steady sales history on the tracked marketplaces, meaning it trades hands regularly and isn't considered particularly rare.

Loose means cartridge or disc only, CIB (complete in box) includes the original box and manual, and sealed means factory-sealed and never opened. For Layla, loose is €46.55 and CIB is €233.01 — CIB commands a premium because original boxes and manuals are fragile and often don't survive.
