Sometimes a quick clobber to the head will do it.
Or maybe a well chosen brick knocked out from above.
If you can't stop these critters, then break a hole in the floor to slow 'em down.
It's up to you to know when to fight - or when to flee! Tension mounts as you hurry Mr.
Do! through the castle's maze, grabbing keys along the way.
Do! has collected all the keys can he unlock the castle door, and open up an extra chance to beat these nasty critters!
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 Mr. Do!'s Castle 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 Mr. Do!'s Castle 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 1983.

Rarity & condition
Only a handful of market sales have been tracked for Mr. Do!'s Castle, 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.
