Yeah that is my biggest issue with the game is the insane amount of needing to be at a specific day and time for all of the interactions.
To me Sandbox games are best when they are just a way to choose who to interact with and when. Not being forced to skip an entire week because you missed that Friday at 7pm window, or had to choose between one love interest vs the other that had the same time slot.
If your going to be using a system like this then please implement a schedule in game for all the girls that you can click on and skip directly to that time of day and location to start that event. don't force me to do the monotonous task over and over of having to skip days and get the time exactly right every time I want to continue with a love interest.
Maybe I am wrong, but with the quantity of bottlenecked gates in this game, I have to assumed that it is intended. That this games "difficulty" doesn't come from hard bosses, or proper inventory / time management, but to overcome tedious boring clicking. That's the challenge to this game, mindless click on locations and skip time time until you find the hidden right time in space. The fact that LI schedules change depending on where the next place you need them to be at. Most if not all tasks can first be completed on days that have the LI farthest away in time from where the next place you need them to be. This happens almost every time, I don't think that happens by accident.
If I had known that was what this game was, I never would have started it. Once that I figure it out, I finished the current build so I could keep the save to remind myself not to do it again a year from now.
