Excellent game. Just excellent.
I saw your note about scope, and I think that's my only real criticism. The levels with the Yarn felt a little to barren, and I would've liked more animation on the main character to add to the adorable factor.But I get it, it's a jam you can only do so much. The only thing I found myself wanting, was a life counter for the boss, it felt like it was taking a long time and I wasn't sure if I was getting close... even if the boss just starts to look more tattered.
Other than that. Beautiful game. The artwork, the music, the story of the yarn with the buttons to track health and the ball of yarn to track your "stamina"... all fit so nicely together. Great work. Good luck with the jam. One of my highest rated games so far for sure.
