Well, it's done. May still update this but it's officially done. I may do a Mine-Field 3 as well, depending on the popularity of this one.
Update 03.07.09: Right, I've sorted out the music issues (well... sorta. More got rid of the source at the expense of the mute button). And I've also fixed some bugs. So... who wants Mine-Field 3?
Update 23.12.09: Merry Christmas everyone! And I'm making a third Minefield for you. It'll have a few different gameplay modes and things. Plenty of nice updates anyway, including power-ups. Definitely power-ups.
