I'm glad you noticed the way the treasure changes... because the associated routines are pretty complicated! :)
I'll bet the treasure routines are complicated! Especially given that there are (from memory) five treasures that can be found in any order. This would be easy in any other adventure authoring language, but not so easy with Adventuron. You should see some of the complicated code in my game, just to do simple things.
And those responses in your game that nobody will ever see? I saw lots of them! That's one reason why I liked it. Apart from yours, 'Talk about love' (at the beginning at least) and mine, there weren't too many games that allowed for obscure commands. I was going to put a "Have you tried?" question at the end of mine, but commented it out when I realised there were so many interesting things to try, especially with the troll. You know, just little things like examining yourself or drinking water at the lake or trying to swim in the lake or singing/dancing/praying/thinking/jumping or trying magic words from other adventures. That sort of thing. That's where some of the funniest responses come from. And that's the difference between a dull game and a fun game. Yours is a fun game. I hope mine is too.
