Great game. So far i played (and loved) Dating My Daughter and Sisterly Lust, but HH is taking it to the next level with more girls, stories and an RPG-system. It sometimes feels a bit grindy because there's no clue where the (soft-)cap of stats are, but i still enjoy it. I downloaded it for free, but after so much fun i'll donate soon for you hard work.
Edit: Can i somehow one time donate instead of a subscription on Patreon?
