SOO much potential!!
suggestions:
allow multiple placements of veg. and animals
allow corrals, or to place animals in one click 'stalls' collect often, 5/10 in each 'stall'
more options of veg. and trees,
allow to buy a 'collect all' 'feed all' item
for 2.0 allow to create orchards, combine items or products : milk- cheese-butter- cream etc. apples- fresh-sauce- juice. strawberries- fresh-jam etc.
