Sweet Hamster Days is a live-action romance sim with a quirky twist: you’re seeing everything through the eyes of a pet hamster. After a strange accident, Kota wakes up not as himself, but as “Hamta”—the pet hamster belonging to the Shiratori sisters, his old childhood friends.
Life as Hamta is cozy and full of affection, but as time goes on, Kota starts to notice how things have changed between the sisters. Old wounds, hidden feelings, and distance have crept into their family, all while he’s stuck in this tiny, furry body.
Sweet Hamster Days mixes visual novel storytelling with crisp live-action scenes, so it feels like you’re really in the room. Every chapter brings new conversations and emotional twists, pulling you closer to the sisters and to Kota’s quiet quest to heal what’s broken.
With full 4K live-action visuals, a cast that sticks with you, and writing from scenario writer Ken Shimomura, the game blends romance, comedy, and a hint of mystery. It’s a gentle, sometimes funny, sometimes bittersweet story about family, friendship, and what it means to reconnect. If you’re looking for a relaxing adventure with a heart—and a hamster—you’ll find it here.
