Saw your ad on a Hearthstone video, curiously... Has been a long time since I was invested in a card game, but looking forward to spending some time in this one when it releases!
Couldn't help but notice the strong influence of Norse mythology themes, which is something I very much do like. Maybe a potential worry is the game being influenced too much? Since it seems the game wants it's own universe maybe this could be hindered by drawing too much inspiration from already existing lore and such? Again, only a potential worry.
Hope the rest of development goes well, and that the game releases as planned! :)
