Like I said a lot is broken, especially SexSim, I'm very sorry but people want to see what they're paying for and I decided it's best to put something out asap so people can be better informed.
If you just want acess to the existing content, the more stable "preview" I recommend just playing for now. As even when functionality is restored, there will still be some limitations due to the games new format (for instance you can't change time of day during sex sim, cause it plays in context). It will take some time to remedy these things and give more freedom outside the core loop.
v0.1.0.a will restore all core functionality, so when you see that release which should be in a couple weeks, you'll know things should work then.
Once again sorry for the trouble, but I hope you now understand what the game is aiming to be and what kind of game you can expect in the futre.
