I'm new to text-based games, and this is the first gamebook that I've played. (I've also played Nameless Quest and a little Zork, but this was less confusing). Having said that, I don't have a whole lot to compare this to, but overall I enjoyed it. I had some difficulty getting from one link to the next, but I think that was a problem with my laptop, and not any fault of yours. Part 1 was disappointingly short, but interesting enough to convince me to seek out this one, and it only took me about seven attempts to survive. I got a different achievement (nice touch, by the way) on every attempt.
Overall, Fatal Island was fun, and I hope to see more of your work in the future.
