Really good game for a first attempt. I think the puzzles are pretty interesting (and definitely well-thought-out ahead of time) and enjoy how most of the environment is linked together.
Warning, light spoilers below.
In my playthrough I only noticed one typo (a missing "E" in the sentence "ach label above a chest describes the contents of a different one of the three chests."). Another thing that's not really a big deal but something you might want to look at is that I was able to pick the same object up multiple times by returning to where I got it from (the coin under the carpet for example). However, I don't have any experience with making Quest gamebooks so I'm not sure if that's something that can be changed.
Overall, it was a really fun puzzle game and I hope to see more content from you in the future.
