Stowaway

In terms of plot, this reads a lot like the old school choose-your-own-adventure gamebooks. Y'know, the ones where you're in a jungle hunting for lost treasure, and you choose to shelter in a cave, and oops! suddenly you've discovered a secret society of mole-people. It's fun and silly, but also a bit jarring, because things just sort of happen without much build-up.

There's at least five different endings from multiple playthroughs, and each were as distinct as the last, with maybe two of the five containing minor puzzle elements whose solution you can kind of stumble on. Only one of the five endings I discovered seemed to have any narrative consistency within the larger framework of being a stowaway on a ship, and it was also the one I found most emotionally satisfying. Nonetheless, I wouldn't consider this to be a fault of the game itself, and more of an incompatibility between what the author is trying to do vs my preferences for interactive fiction.
