So many systems, so many moving parts, and they do nothing but cause frustration. A waste of time, not worth playing even for free.
Only a few have these many problems with game mechanics, so I can safely call "skill issue" here.
I know, people expect only mindless sex from a "porn game", but dev is quite ambitious and has some clever ideas of how he'd like the game to be.
You're free to love it or hate it.
