Computer Version Of Minecraft. I play Xbox, and so the controls for the computer are really complex to me, so if I had a 3DS to play, it'd make life for me that much easier.

Controls:
Circle pad/D-pad: Move, control interfaces (ex: Inventory, etc.)
A button: Jump, Fly
B button: Exit Interface, exit bed
X button: Enter Bed, Minecart, etc.
Y button: Enter Creative
L button: Block
R button: Attack
Lower Screen: See mobs within 30 squares of you, interfaces show up here.
Start: Access interface
Select: Access inventory

Sounds pretty simple to me.
