If you're just trying to get achievements, by all means go ahead, but a warning to anyone who wants to buy this game: your Steam Library will start getting cluttered with this developer's other garbage puzzle games as it pops into your library one by one like a virus. Games that the only way to fully 100% it is from buying their many DLCs and playing through them. Small icons, annoying fairy that flies around (she's the only one who can give you hints so it's damaging to disable her), awful looking badge, complete cash grab of a developer.
Just get a different puzzle game.
