Hi there,
Could you please consider making the final task in a campaing automaticaly unlocked upon meeting the requirements (ie. gathering enough stars)? I keep forgetting that after clicking "Unlock" you also have to click "Accept" (which of course is not the case with normal tasks), and it is so frustrating, when you realize that after going through a bunch of games, and thinking you should have completed the mission by know. I don't know if I am the only one who have issue with this, if yes than don't bother, but if more people have the same issue then you might wanna seriously consider this change.
Oh, and I love your game, thx :)
