Thanks! Here's a document where I explain how to create adventures like this one: https://docs.google.com/document/d/1Q-_vDpEZHyFACZqAO4DRX_Kgerqf8FjF66WGqBXG51A/...
I'm not currently working on this or any other adventure, but I will probably work on some revisions to A Miner Problem this summer when I have some time off my real job.
