Farm Challenge

Nice little game. Makes me think of my game Microgarden.
Great graphics too, and it's nice to see a game where it's obvious the creator knows what the plants actually look like. :)

Is it possible that plants are growing at a random speed?

I can only play the first goal. Is this intended? (from one of the screenshots I thought there were more levels)

I liked it even though there's not much to it. It has that "Harvest Moon" feel.

Can I review this game for my blog here on gamejolt?
