What I understood was that we're supposed to go looking for the Ironmouse "artifacts" (forgot what the disembodied voice called them), then return them to her at the stage, while avoiding the walking stagelight. Had fun especially when I can slightly hear her voice, so I have to pinpoint the item's exact location. Sadly wasn't able to complete the game cause I'm inherently bad at directions so I easily get lost, and light guy kept catching up to me lol
