Very nice, loving the graphical improvements. The cat animations are very nice. I did notice the camera controls are still a little weird with the mouse, are you using Cinemachine for the camera control? It seems like the vertical movement of the camera is locked, it would be nice to be able to angle it so you can look up at high ledges you want to jump to.
I would also recommend removing the collider on the notes. Right now they block your movement and allow the player to jump on them, which feels unintended. Maybe they could be intangible, and once they've been collected they could be made semi-transparent so the player can see at a distance that they've been collected?
Overall I'm very excited to see where this goes, I think the movement mechanics have a lot of potential for cool interactions with good level design. Looking forward to a full release one day, let me know when I can wishlist on steam !
