Watching a playtest takes as long as the playtest, so small teams skip it, and the moment a player got lost is never seen by the person who built the room. Playtest Lens watches it for you. A small Godot add-on logs what the player does and lines the log up with the screen recording. Meta's Muse Spark watches the video and listens to the player thinking out loud. A second Spark pass checks every moment against its clip, the player's words and the event log. You get one page: where the player was confused, stuck or surprised, on the level's map, with the clip and their own words. On a held-out playtest nothing was tuned on, it found where the player was slowed and flagged a possible bug. Live demo: https://naryadchikov.github.io/playtest-lens-demo/
