Just did a playthrough. The Twilek route is the sexier route, from what I could see in the images folder, but I chased the captain, no regrets...
I'm not big on replaying these sort of games just to try all of the routes, but as far as I can see so far there's just the two routes for sexy fun time, plus apparently a third route that involves some locals. I'm guessing sexy fun time with the third main gal may come in a future chapter.
Oh, and Mortze actually has a sexy gal character without Pubic Hair! That's probably not a Mortze first, but lots of pubic hair is kind of his trademark!
Overall, an enjoyable couple of hours. I actually took the time to read through the dialogue, something I don't always do, and the storyline was good enough to keep me interested.
The artwork is awesome as always, but then this is Mortze we are talking about so no surprise there...
Looking forward to the next chapter! Great work Mortze!
