aGaTHoS has updated his Minesweeper game for Nintendo DS.
Release notes:
I’ve released a new version, the link of the first post is updated.
There are many improvements, including various types of input methods as you suggested, clickable question marks, a graphical information top screen with a minimap. And new sizes added.
Still no scores :S, for the next release.
