I finished the game! The linear order of worlds is an interesting idea I haven't seen before. It works well here since it's a shorter jam game. The guide helped a lot. I don't know if I missed instructions somewhere but I didn't realize there was a menu until I saw it in the guide and I had to press every button on the keyboard before I figured out it was assigned to "c".
My favorite world was the one that looked like you were seeing Julie from a stalker's point of view through a telescope. (At least, that was my interpretation of it.) The creepy music sold it very well.
