You call out the 16 carat bags of gold but I find it way funnier that the enemies are DANGEROUS drunkards. This is really cool.
I had a bunch of old Amstrad games I wrote in the 80s that I'll probably never see again. Silly little text adventures mainly, also learned binary by poking character maps... a bit sad they're almost certainly lost forever except for dwindling memories in the haze of childhood, super cool to see some of this stuff being preserved for cultural value if anything.
I didn't know the Amstrad used character graphics, they were uncommon in Australia.
Next time I visit my folks I'll check out and see if they have any of my old disks. I doubt anything survived this long but your post has planted a seed of nostalgia.
