Well that was a lot of fun.
It took a bit of searching to find a game that would work with the Aminet files.
I eventually found a working version of it on archive.org
https://archive.org/details/BlakeStoneAliensOfGoldUSASome of the other versions, for example the DOSBox version didn't work with the Aminet files.
This ran great on my PiStorm32. Nice and fast and I completed the game levels 1-9 on the required difficulty
level two - skilled agent.
I enjoyed this much more than Gloom, and I just thought I'd say as much, because while I was trying to find a working version of the game, I ran across people in forums suggesting that Gloom would be a better option. I would have to say it's worth playing through, but you might need a fast Amiga. I haven't tried it on a slower machine as yet.
