You still don't understand how it is with the spin-off games. Nintendo have very little say. The microtransaction concept isn't even new to the 3DS with Genius Sonority (developer of this game) having already done it with DenpaMen RPG Free last year, as both @Dcubed & I stated.
Also, this is a match 3 puzzle game like Pokémon Link and Pokémon Link Battle, but this time you don't have control in between the combos. Plus, Pokémon Link Battle WAS a game. I still don't understand how you can say it's "not even a game". Just because you didn't like it doesn't mean it's not a game. It's a perfectly valid puzzle game.
