Good but needs help.
I'd intended to post on the Maganic forums, but seeing as the admins there are forum nazis, I'll just review on NG.
As has been stated more times than I've been able to count, something is wrong with how its "randomly" dealing cards. The computer should not get the Parapet 8/10 times and the ++lightning 8/10 times. The computer should not play, blood lust, vampire, blood lust, vampire, etc, over and over while you keep pulling fury. Skilled & master levels already start the computer with a stat bonus and the player with reduced stats. That is more than enough of an evener. Fix. Your. Code. (If the game creator openly admits he cant get past level 4 in master mode [check the Maganic forums], you have a problem .)
Nice try, but aim for playability instead of challenge. Nothing kills a good diea like cramming too much 'challenge' into it.
