The good news is: I have 14 scrolls.
The bad news is: from what I can tell, they are useless.
But I have 14 of them! Yay!
I have 55 (started with 50, gained 5 for reaching lvl 5) and also can't figure out what they are to be used for.
In a similar vein, how do you gain more gold coins? I have completed games (single and multi-player) and won games (both single and multi.) But I have yet to gain any gold coins...
