Hi, thank you for the feedback! In the levels without scrolls, there are books on the floor that contain the shadows meant to be cast. In the future we will work on making it clear to the player what to do. If you get stuck and want to check out some other levels you can use the level selector to jump into the next one
As for the music and SFX, they exist. Maybe we need to tune the base volume, and make it louder. But in the pause menu you can adjust it with the sliders
