Mermaid Madness
Commodore 64 · 1986
About this game
In Mermaid Madness the player takes the role of the weighty mermaid Myrtle who finally, after 112 years, found the man of her dreams: the diver Gordon.
Unfortunately he is not very enthusiastic, flees into the water and jams himself under a ship.

Myrtle's first priority is to save Gordon.
The player navigates Myrtle through an underwater labyrinth (although there a few screens above ground) and collects items.
Those items have to be used in another location to proceed.
It is also important to avoid enemies because touching them reduces her life energy, which can be refilled by finding beer bottles.
There is no scrolling and Gordon's air supply acts as time limit.
About Commodore 64
Released in 1982, the Commodore 64 is the best-selling home computer model of all time, with an enormous software library spanning games, productivity tools, and everything in between. C64 game collecting centers on cassette tapes and floppy disks in their original packaging — physical media that's inherently fragile, so complete, working copies from the era are increasingly prized by retro computing collectors.
Gamevaro tracks Mermaid Madness for Commodore 64 with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.
Adding Mermaid Madness to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This C64 release dates back to 1986.

Rarity & condition
Only a handful of market sales have been tracked for Mermaid Madness, suggesting it doesn't trade hands very often — a sign of relative scarcity compared to more common Commodore 64 titles.
Complete-in-box (CIB) copies typically command a premium over loose cartridges/discs because the original box and manual are more fragile and get discarded or damaged over time — fewer complete sets survive.
