Visually it's great, also combined with card effects, combat and overall/detailed view switching (great solution!). Different types of characters and the need for combining their strengths gave me lots of fun.
A few comments regarding balance (and one possible bug):
- During three runs (two short ones and one of them won) I never found a berserker.
- Wizard seems to be overpowered since he can fire two powerful attacks and then be quickly switched.
- Ability to discard a card without any penalty also might be too strong. Thanks for this it was easy to protect the weak/injured characters.
- Maybe a card count limit (or stricter one if there is any) or more interactions between cards would make me think about actually building my deck. Without this, I just happily accepted all the cards and that seemed to work well.
