MANA has been added to the game, and some of the cards have been altered to synergize with it.
E.g. Shiv, which used to do "attack STEALTH x 5" now does "attack STEALTH x MANA"
MANA is different from the other skills, in that its value reduces by 1 every turn during combat, meaning it is constantly fluctuating in value.
There has also been a general tidying up of some UI issues and minor bugs.
A Strange Key has also been added, in preparation for some additional content which is currently in development.
