I didn't play the update yet but I can see from the comments the problem that happened to make some players stuck.
The game gives the feeling of being a sandbox game. If it is then everything can be viewed but it's not. Hopefully one day the dev turn it to sandbox. Otherwise we don't need saves. We'll have to replay the game every update
I understand what you are saying but no, you won't need to replay every update (from scratch), just make some clever saves here and there, and it will work out
This is a choice based game, with some 'clickable items' to progress sometimes, and definitely not your typical harem game... It's more ... realistic. You will have to do some effort to find the right way to the hart of every lovely lady, and maybe get some nice action
Some ladies will come in pairs though, because they are friends.
The reason maybe players have got stuck, is that the game is incomplete and only covers three days at the moment, and only a limited amount of stuff can be accomplished each day.
So what happens is that the player has to progress to a certain point with Vanessa for instance on the Monday evening, in order to unlock content with the barmaid on Tuesday evening.
If the player does not get far enough on Monday they can still meet Vanessa at the pub on Tuesday and unlock the next part, but then they basically run out of game before they can get the barmaid content the next day. The reason is that the next day is then Wednesday, and Wednesday doesn't exist in the game yet, so that's why they get stuck.
After the game has been developed further with more days it will be possible to progress by just trying again on subsequent days, so players will not get stuck as they do now.
That's not to say it will ever be possible to just keep going and get all of the game content in a single playthrough. It's a multiple paths/endings game, so some choices will always lead to some content being seen and other content being locked out.
