The Simpsons: Bart vs. The Space Mutants
Commodore 64 · 1991
About this game
The Space Mutants is a platform game where the player goes into the role of Bart Simpson (from the TV show The Simpsons) and must stop the Space Mutants from invading Springfield.
On each of the five levels, Bart must collect (or get rid of) the ingredients that the Space Mutants are planning to use to build their machine, such as purple objects or balloons.

He also has to collect enough "proof" of the aliens existence (brown coins left behind when they are jumped on), so his family members will help him when he meets a boss (characters such as Nelson and Sideshow Bob).
This won't be easy since the Space Mutants are "using" human bodies as disguise.
In order to discover who are the real Space Mutants, Bart must use his X-ray Specs.
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.

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.
