It's always cool to see people making text based/imagination oriented experiences.
There was also some inconsistent formatting (missing newlines on some output, some cases where newlines between choice options were followed by a space while others weren't) and a few typos. These are minor, but since non-linear text is very difficult to proof read, it's good to catch that stuff as early as possible.
It might also be a good idea to santise inputs a bit - it was difficult to know whether I'd reached the end of what had been written so far, or if I had just put text in where a number was expected.
If you keep working on the project, good luck. I'd be interested to know where that treasure map leads!
