Great Logic Art

Really like this app - but it won't let me purchase any in-app purchases

Good design, and like breaking up the puzzle into manageable pieces on the smaller screen of an iPad mini but constantly switching back and forth between black and white "pen" tedious. Would be nice to have completed blocks in a row highlighted, and auto fill of empty spaces when all coloured squares in row or column done

Good game

Good logic game. Not sure why it won't let me purchase the next levels...
