I would find it cool if the pic of the necromancer "evolved" as you gain souls/upgrades... getting a more sinister look, or whatever. But it would be just an aesthetic thing ^_^
nice game!
It felt strange to play it at first, but once you get the hang of how things work it's a nice little game. Can be a bit frustrating at times when the card(s) you need just won't show up despite how many discard 3s you play, but overall a nice product anyway. :)
