When you stall, you can actually pause the game and hit any button till stall warning disappears and it will work like charm. Not abusing a bug tho just feature ;)
The game is fun, but ends too quickly and lack of end game* content. ( I got to a point where I got a new skill point but didin't have anything to spend on lvl 72.)
The game is good, don't get me wrong. But probably not a right choice for the badge of the day. Too much frustation when you have limited time to complete it.
