Wow, I can't believe someone did this...it's my childhood game! :P One comment is that you might wanna make it clear that classic costs money. e.g. Yes Buy for $0.99 on unlock classic mode dialog
Looks awesome. I am a huge fan of Minesweeper and implemented my own awhile back because the implementations I could find were pretty lousy.
@jbrooksuk I disliked that aspect of Minesweeper so much that my version exposes the outermost layer of mine counts, so you don't have to start off the game by guessing and possibly dying instantly. :) Might be a nice feature to implement in this version as well.
