In order to do this you need to find and destroy each X-14 Tantalus Ray, powered by cells from the big purple Space Amoeba.
The game begins with a top-down map of the mothership.
This is the level select screen, where you can walk around and choose the next level you want to enter.
On each level, you have to find the exit; if this is one of the levels with a Tantalus Ray, you've got to destroy the Ray before exiting.
Once you reach the exit, you're back on the map of the mothership.
The levels are typically full of enemy creatures and hazards.
If Keen gets shot or touched, or falls into a pit or hazard, he dies, and you're booted out of the level back to the overhead map and lose one life.
Thankfully, Keen can defeat some of the enemies with his raygun.
He also has a pogo stick which allows him to jump very high.
Other items to find include keycards that open locked doors and bonus items which give score (Keen gets an extra life if he collects enough score).
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 Exploding Fist + 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 Exploding Fist + 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 1988.

Rarity & condition
Only a handful of market sales have been tracked for Exploding Fist +, 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.
