I still say it should stay on PC.
On a side note however:
I think it would fit the 3DS more, mainly because of the Touch Screen and the fact you could fit many controls down there, or better the inventory and menus.And if there is a problem with controls there is always the circle pad pro.
I'm not even going to say about the Wii U Considering its practically the same thing, bottom:inventory/gui, top:player view
And maybe Badspot would make a deal with Nintendo considering if Blockland did require copy of the circle pad pro that would be an extra peripheral made by Nintendo you have to buy to play the game.
Many possibilities are possible, such as the Circle pad pro being bundled with Blockland if sold.
Estimated purchase amount:$45.65 Bundled with Circle Pad Pro
Or the game being sold on its own for the reqular $39.99 and Circle pad pro optional, sold seperately.
Of course however I'm sure its never going to happen.
