Good stuff, but needs work
Ive played both this and the previous version, I must admit they are awesome BUT, I personally would like you to make a few changes:
1. Would be great if you create or improve the campaign mode's difficulty settings. By this I mean sometimes the cards I get are constantly cheap while my enemy get the high healing, damaging and invulnerability cards and I get stuck with "Give one Taint" or "Get 4 health back" over and over. I know you might of heard this a lot, but PLEASE, if its gonna be an unfair fight, make it late game! That would be more logical.
2. I would like some form of a deck builder like others mentioned... could be basic even, like each round you have a choice to instantly get a particular card or so. Knowing the game's difficulty however I i'm sure the computer will just get something better.
3. Game atmosphere feels repetitive... a change of music every few turns or so can fix that up for me.
