Well done!
Very good work with the aesthetics, art is cute and coherent, sound design is on point and the interactions are juicy.
I'm not much of a puzzle person, so don't have much to add on puzzle design.
As a casual player, difficulty scaling was pretty good.
Regarding input, I prefered playing with the mouse, dragging the paths, I wish holding RMB would undo continously.
A small suggestion for the main menu would be increasing the size of the "Play" button a bit.
Overall, excellent work!
