You can play the game here on Archive.org, or you can download a copy from an abandonware site and play it in DOSBox Staging.

Here’s all the physical documentation you’ll need, such as the short story, how to play manual, and an in-world map (you’ll have to draw your own, but it’ll give you a rough idea of the land. If you find map making tedious, you could use a map someone else made).

Lastly, you’ll need this interactive copy protection wheel when it prompts you for a combination in game.

Good luck! :D
