For all those saying "its Nintendo what do you expect"
The developer sets the price for their eShop games.
The same thing happens on all consoles, Angry Birds: Star Wars is £30 on the PS4 in the UK, for a game that is a couple of £ on the app store.
It must be the way the developers view the console ecosystem. Sell high and sell a few on consoles VS sell low and sell loads on mobile.
