Thanks! Yep, I agree that the hook / mass appeal isn't as strong unfortunately :p
I'm glad you love the music; Shake onigiri did an awesome job with it! I also really like the facial expressions, they were done in the final stretch of development but I think it added a lot of character and I enjoyed learning to do sub-pixel animations for them!
I actually have a working rewind time implementation from my post-jam Edna version but didn't have time to integrate in here. Thinking about it now, since everything snaps, it's possible to do undo like in a regular grid based puzzle game and I'll work on adding that in a post-jam version.
