It's pretty good, but the timer runs out way too quickly. I have no time to harvest all the pumpkins and plant new ones because it runs out first. Please either extend the timer or have a toolbar like someone else suggested.
I agree that its too short, we were trying to balance the game so that you would have something to do the entire time. Even if we set the timer to 2 min the last 30 sec were sometimes kind of boring with no gnomes
