This is great, such a neat puzzle game! It was a bit hard for me to immediately grasp and remember what each block does, but this is a matter of experience, I think. I think I might continue playing this casually from time to time!
Also I really liked the way music changed depending on what block you hold. Such a cool little thing, but I imagine you had to compose a whole different arrangement of the main theme for some of them, and this is some extreme dedication.
