It seems they've finally fixed most of the game's bugs. According to the developer, version 1.09 is the most stable, and they recommend starting a new game to avoid errors. Personally, I'll wait for the DLC and some quality-of-life improvements, like less grinding and event tweaks, before playing it. The good news is that they're already addressing the game's issues. Let's hope the DLC brings plenty of quality erotic content that enriches the game's storyline and encourages players to explore the NTR surrounding the little sister.
