Very good game, with quite decent dialogue although the personality of the protagonist is a bit passive and denialist with what he wants.
let's see how the developer can introduce Abby into the harem without messing it up too much. Because and this is assumption if she is in love at the point she is currently she would have to show quite a few problems since she would feel excluded and hurt
SPOILER SPOILER
topic already widely discussed in other posts. considering that Patreon has vetoed incestuous relationships, even between stepfather and stepdaughter, here is the malice... the "side" stories linked but not integrated into the game (relationship between Becca and Frank... for sure Becca is Frank's biological daughter). another trick is to continue the story, until its last episode/update. in this way, you can exploit Patreon until the end, and also with the hope that the violation is not detected, and the game is kept on the page. now, a little personal consideration of mine... I wonder HOW the developer wants to get Abby into the DPG. Abby is very jealous, and she hates betrayal. if she finds out about the DPG, it can't end well... if she finds out because of Lilith, but... what if she finds out about May or Becca? or both at the same time... or... in the next updates, we expect the trip to Beth's parents' resort. in this location, we expect a foursome, or almost, that includes Becca and Vanessa, Beth and Frank. It's obvious that Becca will do something with Frank, even if Vanessa doesn't participate. What if, by pure chance, Abby were to secretly observe, and discover the relationship with Becca? SHOCKING. Maybe, it can start from there, the Abby/Frank relationship.
(a rare thing for me, idk why)...but i'm starting to kick myself for renaming the Li's these days, since I forget what they're original names are when I do I play so many damn VN's
