Thanks for the comment, and I'm glad you're enjoying it. I'm not sure how many things you've collected so far, but the jar of acid is at least one item you'll need to get for any of the better endings. Try spending some time around the pond searching for the source if you haven't found it already. Also, the cave has a lot of important items inside if you can find a way to move the stones away from the entrance. Both inside the cave and at the pond have moments where you must just wait for a short while to have things appear, which is hinted at by certain comments in the text. (For example: It would be foolish to continue without letting my eyes adjust to the dark.)
If I've guessed wrong and you've already figured out those things I've mentioned, or if I was a bit too vague with my hints, let me know and I'd be happy to explain a bit more.
