Mom or Sister

Mom or Sisters is a story-driven casual game that lets you unlock multiple routes and storylines. What happens at the end depends on what you do—especially how your choices shift the way you relate to the people you care about. Will you be able to get what you want and experience close, intimate moments with them?

Throughout the game, you’ll meet varied story events where your progress hinges on the decisions you make. Each choice changes the dynamic between you and your loved ones, gradually opening the door to deeper conversations and unlocking new, exciting animation scenes. Of course, you can also choose to simply watch from the sidelines—but that path tends to push them further away.

Key Features

1) Incestuous Allure

Take the seduction-focused route. You’ll work to raise each character’s “Attraction Points” using deliberate actions. Their feelings can build from small, meaningful looks all the way to explicit desires—crossing lines in a way that becomes increasingly hard to reverse.

2) Voyeuristic Control

If you want a darker playstyle, you can try to undermine trust and drag their Attraction Points into negative territory. As resentment grows, they may distance themselves from you—yet this also creates opportunities to observe them as their behavior changes, including encounters with strangers.

3) Relationship That Reacts to You

Your decisions reshape attitudes and personalities. One moment—like a hug—might deepen affection, or it could set betrayal in motion. Conversations and actions aren’t just cosmetic; they carry lasting consequences that force you to weigh every move.

4) Attraction Points System

Increase your standing by using gifts, emotional pressure, or physical closeness. Higher scores can unlock private moments, while lower scores may lead to more rebellious or desperate responses.

5) Consequences That Trigger Scene Changes

Cross certain thresholds to unlock irreversible story sequences. For example, reaching +100 points in the incest-focused path—or hitting -100 for voyeurism—can lock you into events that can’t be undone. Depending on your choices, your characters might participate willingly, or they might embarrass you publicly by showing off new partners.

Player Feedback

One player described early releases (like a 0.1) as a teaser, expecting only a short introduction to key characters and not much else yet. They noted that it’s reasonable to give creators some leeway at this stage, and encouraged others to watch for progress and revisit later.

Another comment mentioned that, in terms of rendering quality, the game looks better than many similar RPGM projects they’ve seen. They expressed confidence in the project due to the involvement of 3diddly, praising both the visual output and the overall story potential, while also hoping the game continues to improve. They compared it to other branching experiences and said they hope Mom or Sister reaches a level at least comparable to favorites from the genre.
