I spent some time playing Puzzle de Harvest Moon a few months ago and I liked how it’s not a clone of anything on the market. In Puzzle de Harvest Moon you grow crops by picking water and fertilizer from your five random items. Once a crop grows you have to scratch the screen to pick it and get points. While you’re busy farming, three other players are planting crops on the same field too.
Since the concept is out of the ordinary, Natsume is trying a unique approach to showcase Puzzle de Harvest Moon. They made a scaled down, playable flash demo (thanks for the link IceAmp!). It starts off extremely slow because you have to sit through a tutorial, but there is no better way than seeing if Puzzle de Harvest Moon is for you than trying it out.
