I do love amassing an army of fairies to do my bidding.
I like the basic mechanic, but I wish it was easier to gather your fairies after you send them to pick up something and they return to the gap. Lots of walking otherwise. Being able to zoom in or out could be useful too. Though I haven't played Pikmin before so I don't know if the game should have these things or not.
The art is very cute and I like the 2.5D style and the animations.
