Though the presentation is rudimentary, it's nothing unusual for a jam VN, and I do think the reveal is visually striking. On the narrative side, the twist could maybe have used more buildup, a more gradual escalation of weirdness; there's a bit of a disconnect in how different the two halves feel. The chamber play-esque premise is a good exercise in keeping the scope small for a game jam project (let alone someone's first visual novel, which it is always an achievement to get released!)
