Well, I already decided to uninstall From Dust after completing 6 out of 13 chapters from the story and 11 out of 30 challenges. The solutions to the story mode chapters and challenges were usually pretty obvious. The clunky cursor movement was the biggest challenge, specially during the timed challenges.
The color palette was nice and the interplay of the elements had its cool moments. I can't say it was worth the $4 I paid during the Steam Summer sale. I didn't feel any sense of reward or accomplishment completing about 40% of the game. Think of this post more as a public service announcement.
