I played the first two tutorial parts, but got stuck on the third hello world. I said that I needed 4 words, I got "to" but not the other words.
Also I didn't realize that I could turn the blocks at first by clicking on the arrow, I expected it to be symbols for rotating for ex mobile controls.
Also it's a little confusing that there's 4 sides on the cube but two are obscured by the other cubes unless it's a corner piece.
That said, great art and ambience feel to it!
