Let's see.
As there is no hints in game itself, I just started playing as usual, hoping for them to appear later.
Nothing appeared though, but strange things started to happen.
(A lot of words ahead, so under spoiler)
So, in summary.
I cannot raise my lust any further, my landlady's lust/horny do not raise either, all actions are locked due to lack of stats I cannot raise due to unknown reason, no interaction with other chars except some random scenes, there is no way to figure out of how to trigger anything as there is no hints in UI, no hints in dialogues, time spending is very annoying as I have no prior idea of how much time any action consumes and thus I'm missing (maybe even more than I'm aware of) those actions/event that are supposed to push the progress further, some strange "glitches" occur here and there, gameflow has no sense as I cannot get if the sequence of events is supposed to be so or it's just bugged...
It just looks like all the events have happened in the first 2-3 days of play and there in nothing ahead or it's locked too heavily under the gameplay... features.
... from what I've read in walkthrough, I assume that those triggers I should have already are miserably failed, and I have not a slightest idea of how to unlock them, or at least make them work on a new game if I'd start one.
I believe I described it to you in sufficient quantity of words for you to feel my frustration from the game experience. I'd really like to play and enjoy it (I believe there are much more scenes somewhere ahead), but eh, no idea of how to reach there with all those randomly occuring... things. I could play further and MAYBE something would change after all for the better, but what if it would not, yes?
