Sliding Doors is a narrative-driven interactive story built in Twine (SugarCube) about how small, everyday choices shape the way we see others, and ourselves. It mixes story and system by using branching dialogue, variables, and light memory-based minigames to turn emotional decisions into actual gameplay.

​

The player follows Blake Saunders, a painter who’s lost his sense of purpose. Over the course of a week, he meets three fellow commuters whose stories touch on ambition, grief, and regret. Each relationship changes based on how closely the player listens and responds, leading to different endings and reflections on connection, identity and creativity. When Blake paints, players pick words and themes inspired by earlier conversations, turning memory and an eye-for-detail into the key mechanics. Getting it right feels rewarding, as Blake earns money from his art, which can then be spent on meaningful gifts that shift how each characters' story ends.

​

The game runs on conditional scripting and variable tracking, making story and gameplay feel fully intertwined. Every conversation, choice and gift shows how well the player has understood the people around them in this cosy, sonder visual novel.
