This is an unfinished TADS game with some good content and promise.
You get isekai'd by two weirdos into a purple portal. The world you enter has lots of pipes and knobs and rust (feels kind of mystlike) as well as a critter (doesn't feel Mystlike).
The cool thing about the game is all the mushrooms (which you can take multiple chunks of for each fungus). Through experimentation and consultation you can determine the unique properties of each, which are quite complex. The game models liquids, multiple objects, movable 'door'-like objects, and NPCs.
A more full version would definitely benefit from hints and from a general pass of bugfixes and better implementation. I had to read two people's transcripts to see how to progress. Overall though I had a good time, it feels like fun interaction.
