It is a shame that the developer has been caught in such a situation that has hindered the progress of this game for so long. I am hopeful that his return is not a fluke, but I won't hold my breath until I see some progress made on the actual game. The game definitely feels like it is approaching or is in the final stages so I think one or two more chapters is what is needed to wrap things up nicely. I don't think there is much left to explore at this point in the story without resorting to redundancy.
Also, is there anything similar to this with only one love interest and no incest involved? Most games here suffer from a lack of depth due to multiple love interests, as the content is spread too thin among all the girls, leaving little room for meaningful development between the MC and each individual girl. Please, only games with a male main character, nothing like AWAM.
