Also :
1) chinese version is in production
2) game is finished with all content added
3) dev is now working full time on the append (apparently, content is mapped, all there is left is the development itself. ETA between spring and summer 2023 - although the dev remind that the original game release was reported 3 times, so the append ETA is not final).
3b) following the lot of demand for it, the dev intend to feature the side girls (claret, Iris and Milla) a lot more.
no more detail on the append for the moment.
