FarmLand is a charming, $2 casual strategy game for the iPhone from iMouse. It looks good, and it's fun to play. The game starts slowly, but in spite of its repetitiveness, becomes an increasingly addictive diversion.
When the game starts, several options are locked away-"Survival Mode" and mini-games are unavailable until you've made some decent progress in the game's Adventure mode. When Adventure mode gets underway, an in-game tutorial explains most of what you'll need to know.
