I also still remember the Commodore 64 very well! We played tons of cool games on there, but can't recall one where we had to escape a prison...
Anyhow, I love the technological history you bring into your story. It really brings me back to the beginning of the Vic 20, the first computer I ever owned.
Thanks a lot again for all of this, congratulations on the 72 Reputation score and namaste :)
This game was not on the Commodore 64, but on the Amstrad.
