147 days and I had them all even the unfinished Nene (I just needed the ring kek)
Only Hun-ni was available in the morning which made having a straight grind session of maximizing all girls stop once I had Huni-ni's Tasks.
I think the way you grind for better stats is a good idea but maybe raise the cost for reward to get the most of the currency after the halfway point of one stat was reached money almost was too easy to get.
The Art is great and RiceKappa really rustles my jimmies, hope you can expand maybe even arts of the Bush and the Bree and the bush we hid in. Maybe more saucy rewards are in order?
Can't wait to see updates, hope it doesn't get too hard....
No pun intended.
