Lovely(!) art and a crawl inside a giant creature without the details some others dwell on. A big puzzle to get a BIG price. Would do well in a campaign to gather giant allies, too.
I’d perhaps add a wise ranger in the village hinting on the mechanics, so it isn’t as much deadly try and error (that’s my D&D brain talking again).
The PDF was really trying not to get printed. I was able to compress it to 1/100 of its size to get it on paper.
