Like the gentleman before stated, I too have a problem with achievements.
First of all, I've played on Android.
I've deliberately checked and I did, indeed, meet the requirements to do the "chain 10 soft/medium paizuri" achievements, but they didn't unlock (only hard did, for some reason).
However, I have unlocked the "reach intensity 5 during blowjob", despite... Only playing BJ mini-game once, (and only reaching intensity 3).
Could it be that requirements for these achievements have been switched in the code?
Another thing I've noticed is that in stats screen, it says "rituals with Deolia" twice, instead of two different names.
I assume that I can't see some of the nightmares and events as well, as I had used quite a bit of breakpoints without anything new happening...
However, despite the small stuff like this, game is amazing!!! It runs brilliantly on my shabby phone. Zuri animation (as well as static scenes) is awesome! Other kinds of sex scenes are good too, of course, but it's just that my head is only filled with titty sex.
I hope the bug report wasn't discouraging, because I really liked my time with my big titty paizuri nun.
Thank you for your hard work!
