Best wishes! I know how hard it is to make a good branched story that will "work".
As for endings, that's another thing that I kind of missed, only 1 type of good ending for each girl mostly, in maid setting game I would expect marriage good ending or maid good ending for example, but that's just problem with my expectations I guess. :)
Obviously I was joking about the expansion (and the steam card), but in all honestly, I would love to learn more about 3 side maids (and have more interaction with them), they seemed interesting, also would love to learn more about Pa Zong (somehow I liked her the most).
Good luck with the next game!
