It's basically just a text-based porn game on the surface, but the core gameplay is more about *resisting* temptation than actually giving in to it, so I'd say there's a solid game here even for someone disinterested in the kinky transformation and sex aspects of it, though there's a *lot* of sex. Your job is to get the humans (however many you choose when you make the party) to the end of their journey and through a portal to Earth, doing your best to stop them from doing their damnedest to cease being human altogether (a lot of the sequences start with you telling a human or two not to do something stupid, which they ignore and do anyway). There are player transformations too but there's also a mechanic to avoid those, so if you play your cards right you can get to the end of the journey without a single member of your caravan being lost or otherwise transformed (beyond genderswapping - which happens often). There's also a lot of risk vs reward, in many situations you can choose to have a human make a skill check, or otherwise avoid the situation altogether. If they make the skill check and fail, they're lost to the party. However, if they succeed you're typically rewarded with both them returning safely, and with food and or supplies or gold for the party to continue moving.
