Everything from movement to tool use and menu navigation is done via the stylus. It's all executed very nicely but surely the option for a D-pad-and-buttons control scheme would have been easy to implement? Playing one-handed for any protracted length of time left us with some serious arm cramps. The other main problem lies with storing items. Your rucksack holds plenty of stuff but not all identical items automatically stack.
While X amount of the same crop neatly falls into one slot, other stuff, such as chicken eggs, fill one slot each. As such, you spend a silly amount of time fiddling with your sack. But that's a minor moan in what's otherwise a delightfully – worryingly – addictive Harvest title.
