Hi hexux, thanks for playing our game, I hope you enjoyed it!
In response to your questions, we don't have a specific date for the next update, but we do have a tentative one, which would be around the next 10 days (or even a little sooner). We invite you to follow us to stay updated on the game's news.
We haven't considered adding Russian as a language option because we don't have enough of an audience that speaks it, and we don't have a trusted translator, but it's something we'll try to consider for future updates!
Regarding the girls, it's quite possible that some of the endings could lead to any of them getting pregnant, but I won't spoil anything. And finally, the idea is for all the girls to appear eventually.
Take care, and I hope you're doing well!
