Can you list some games similar in playstyle to HH?
Mystic Manor by Jekei (most like HH). Wartribe Academy by Mr. Rooster. Lucky Paradox by Stawer. Love's Champion by Grimaga. Hero's Harem Guild by Komisari. The SHRiNK by OneManVN. A House in the Rift by Zanith. Confined with Goddess by Enroniverse (the simplest in terms of progression, and it's the only one that is actually complete). (I said half a dozen and I deliver). Good clean sandbox harem fun: no mind break (psychic murder), no MC f**king his own mother and sister.
