I always find it interesting to look through unfinished projects, and this one was doubly fascinating for the fact that it actually has at least one ending!
The telltale signs of an early project are present everywhere from the obvious intended breadth of story options available to the variety of settings and tones the story can take. It really gives the feeling of kinda throwing everything at the wall in an attempt at a grand adventure. And sometimes it kinda works and other times its a bit odd. There are some spelling errors or some weird HTML issues it seems, but of course this was your first big game attempt and its over a decade old (my game attempts from a decade ago didn't even have code). It's a charming preview of what was to eventually become TSV, and I can see little parts here or there that remind me of later projects. Specifically the idea of characters finding themselves locked in a weird place, and the fact there's main characters who are siblings.
I did go through every option I could find so I did hit a number of "Double-click to edit" dead ends, but I was genuinely surprised by how many times the story continued through. There was a couple parts where I did genuinely wish the story continued through, and frankly one I think could be broken into its own standalone game possibly (I won't spoil those here though).
It may not have been finished, and likely never will be, but I'm happy it led to the start of your indie dev career proper!
