Tomboy Supremacy

A US Army veteran comes home to Southern Missouri after four years away, and immediately regrets it. His younger sister Cheyenne is a tsundere with a full-blown brother complex, his other sister Mary-Sue is locked in a blood feud with the local squirrel population, and his older half-sister Luna shares a body with Cozmo, an insane, alcoholic teddy bear who apparently gets a say in things.

The plot is basically an excuse to move between family members and their respective disasters, and the game leans hard on comedy over anything resembling seriousness. It's a parody of rural American life first, with the harem antics riding shotgun.

You spend most of your time reading and picking through dialogue as the veteran gets pulled into each sister's mess, with the relationships escalating from there. It plays like a story-driven visual novel rather than a stat-grinding sim, and it says outright that it isn't meant to be taken seriously.
