About this game
The game centres on a boy called Lee and his faithful dog Ralph.
We're introduced to Lee from the dog's perspective after waking up to find his owner sleepwalking through his bedroom window.

Ralph leaps after him and the player then takes control of what happens next.
Throughout the game Lee will relentlessly walk in the direction he is facing, the problem is there are objects and pitfalls in his path that can ultimately wake him up or even kill him.
The player can monitor Lee's sleep level with a bar at the top of the screen.
If the bar reaches zero, Lee wakes up and the player loses a life.
If this happens three (or five depending on settings) times the game is lost.
The player controls Ralph the dog in order to manipulate either Lee, or the objects he is likely to walk into, to see him safely to the end of a level.
The frequency of these pitfalls increases as each level progresses and, as it does, the player has to spend more time strategically neutralising threats, far in advance of Lee's actual position in the level.
Although it is possible for Lee to die, resulting in a loss of life and restart of the level for the player, Ralph is invincible, surviving otherwise fatal incidents with comedic effect.
If all the levels are successfully completed Lee finally returns to his bed and crawls back in.
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 Sleepwalker 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 Sleepwalker 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 1993.

Rarity & condition
Only a handful of market sales have been tracked for Sleepwalker, 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.
