To be honest, you DO need a walkthrough for the gallery and for interactive sex scenes with triggers. In the feather scene with the youngest one at nighttime, it's not clearly described or translated. First, you can see a hand symbol when you click on her when entering her room after 2300. You click on that, click the blanket to take it off, then go to backpack, select feather and touch her feet. Next, touch her ribs that are facing you (the area of her ribs on her side under her breast) and she'll turn again.
FYI.. in the fight scene, I found out that switching between uppercut-punch-defend and punch-defend-uppercut seemed to give fairly good odds of winning.
Started a new save and had almost no bugs. I only had one strange bug that wasn't game breaking but had to do with using the save function. I had showered and then entered Mia's room to start a scene and before clicking on her, I went to save it and it triggered a strange traceback error.
Code:
While running game code:
File "renpy/common/00action_file.rpy", line 372, in __call__
renpy.save(fn, extra_info=save_name)
PicklingError: Can't pickle <type 'function'>: attribute lookup __builtin__.function failed
I just rolled back, exited the room, re-entered it and was able to save.
