It's pretty fun to play, and charming. It's just lacking a bit I feel in gameplay..
I know it's a free-to-play 3DS game, but I just feel that for something to have microtransactions like this, there should be more things to do. Unless I've not unlocked much yet since I'm still near the start of the game, there's not much difference between the levels so for me, I see it getting boring very quickly.
Gem apples really don't seem much like a "premium currency" as like 90% of other paid stuff is, since it's really easy to get loads of them and you don't really spend very many (I see this changing when you get to higher levels and stuff though), the items are boring as there seems to be no way or upgrading them or anything like that, I couldn't even find a way to sell items which I don't need anymore!
I've not played this with any friends yet, but I think it'll be a lot more fun once I do, since it's boring and quite easy so far..
The Amiibo addition is a nice touch though, shame you don't get very much stuff from them considering how much Amiibos are. I've not yet tried to see if the Animal crossing Amiibo cards work, I have a feeling they wont though since very few things outside of Animal Crossing games will take them.
Overall: Cute game, not much differences in the levels makes it boring pretty fast.
The game may change when I play it a bit more, since, like I said, I'm not very far into it. I've only gotten to the first level that you unlock using Gem Apples (A cheap concept and kinda annoying since, even though the first level only costs 1 apple, I Presume that'll rapidly grow and become stupidly expensive..). I understand where they're comming from with the Gem Apples, I mean, how else are they going to get money from it? But It's just really annoying, could we just have 1 Free-to-play game that doesn't require money?
