Would that be an issue with the stylus? I mean control-wise the Minecraft homebrew for the original NDS wasn't that bad.
In fact I think i would prefer the stylus to dual-analogue.
It would for me. I tried that sort of control setup on Mario 64 DS and it was just awful for me. I do have dyspraxia though.
Mario is a third-person platformer. Minecraft is a first-person game with very little need for "precise" platforming. As a player of the PC version stylus> dual-analogue for me. The stylus takes the role of the mouse in such a scenario.
