The game critiques the very premise of "raising" a sibling who is not blood-related. The moment you accept the role of guardian, you also accept a position of absolute power. The "correct" choices are those that acknowledge this power imbalance and actively dismantle it — which the game rarely rewards with explicit scenes, hence its niche reputation.
Unofficial APK ports sometimes circulate in enthusiast communities, though these carry security risks and lack official support.
The best feature of the Android version is portability with touch controls , allowing you to raise your sisters correctly anywhere, without needing a laptop.
