If I can say anything about the game as of right now.
Trying to do anything in terms of like moving from room to room is super time consuming and not in the fun way. (that super long hallway is just kinda there. fix: menu system to go into each girls room( not sure if your planning later on for each girl to have their own personality and or room decor but at moment it's there and it takes a while.)
"Grind" is just kinda having the game run in the background which is just a big meh.
Figuring out what the stats of each girl is at moment is annoying which expedites the 1st problem. (For both planner and incubator having a way of checking their stats while there would be a big plus).
This stuff bellow is just more ideas for development
Incubator at the moment is super annoying to deal with if you want to make one super girl( having someway of being like yes this one will be a futa or not would help and maybe later on in the game having an upgrade to it that allows for specific stat distribution or whatevs).
Potions are kinda garbage in the making process(the menu is wonky and trying to make several potions is a whole lot of menu navigation that just annoying as shit to deal with.), using process(part of problem 1 and 3 going back and forth and back and forth.), and effect(it just being a stat potion is fine but having it do more like overcap would be cool).
Money is worthless you can just spend the 3 or so hours building up wood and stone then using it for money but after that not much else. (obviously going to change so not really something to note).
Besides that um not really sure what the current endgame is for the game. Like I get it make uber strong sexy ladies, but I guess more of what's the end goal for them. Not sure if there is going to be a plot but if you are planning something like that
