@sfortenn Foils are purely cosmetic, just something fun to do if you have extras of certain cards. It's 20 for commons, 10 for uncommons, 5 for rares, and 3 for epics. I believe all you do is hit the button and it makes the selected card the foiled version if you have the required amount
@Scorp I though it was quite funny. Another thing, if you look at the top comments for every game it's the same lame jokes repeated with x game instead of y game in said lame joke. Nothing wrong with jokes in the comments esp. fresh, unique ones :]
Bug: After buying a weapon upgrade(not sure about armor) and you have extra money left over go to the spells shop. Do any battle then return to the upgrades shop. You will only have the money from your last battle and none of your leftover money from before.
Gah, sorry for the double post. Just acknowledging another Mac related issue.
@cake there is no need in the game to even toggle invis while moving. Do it from a safe place and continue on with the screen.
I'm playing on a Mac and had 0 problems with this game whatsoever.
