I played through all the available content in this game over the past 2 days and there are so many confusing design choices...
Overall the game is pretty cool and I like the management aspect of it until it all kind of falls apart in a never ending grind to power level Adventuring. I don't really have any thoughts on this system since it's clearly incomplete. Having prior knowledge of what to do in the early game speeds up your progress far too much compared to blind experimentation because of how character XP is awarded, and how beneficial certain items are compared to others. Progress is determined heavily by how you allocate character XP, and knowing the best answer can save you like an hour or so (I only know this because my game crashed at some point on my blind run and the save file got wiped.)
I never 'organically' figured out how to get Gina. After reading the thread the rock you destroy is not obvious enough, and not alluded to by the fortune teller. This felt kinda bad after I learned she was actually something I could unlock.
It is also very weird that you don't actually require the Axe to do the Lumberjack activity at the start of the game, and it should probably just be a forced free acquisition when you meet the vendor as part of a tutorial to explain tools or something.
My main gripe with the game, is that the stat XP system currently in game is just awful. You are actively punished for diversifying activities for the girls since tunneling a single stat dwarfs any other form of XP gain into the dirt through random skill ups and respecing. Studying was completely devalued after getting any single stat on a girl above ~40. There are also some bug with respecing that allow you to keep your current stat points, effectively doubling your stats at the cost of resetting your perks. As you can imagine, this is always worth doing and speeds up the grind immensely.
Anyway, I look forward to future versions of the game. You should seriously consider capping the stat system you have in place and re-balancing around girls having a finite amount of stats inst
