The biggest pain point I have right now is that the tab key is used for text completion (which is important if you don't want to spend all your time consulting lists of words), but every time you use it, it *also* changes focus out of the text pane. it's absolutely infuriating.
I think as long as I avoid the sex scenes the user interface is mostly do-able. I fumbled around for like 10 minutes trying to seggs the first girl who seemed DTF, and I has having 80s Zork PTSD ("I don't know how to remove clothing", etc etc). Ugh. Hopefully future scenes are more voyeuristic so I can enjoy the scene without having to fuck around with the interface.
