This game is fascinating. Thanks for this.
A couple small critiques:
- Is there a sell all command? "SELL * B" or "SELL ALL B"?
- I don't know how deep this story is going (great so far) but it seemed like a pretty big text dump right at the start. I think you can get up to the level 4 nautical-word quest from the beginning, through a chain of 20-25 commands? It seems like that if that were split into a couple parts with some arcade game in between it might be better pacing. The snippets that I've found after that on levels 5-6 are nice.
My 2¢. Keep it up!
