Love the concept . Fairly hard, but I felt like I was getting better at it each time I tried a run, so its probably just me slowly going through the learning curve.
Didnt run into any glitches.
Two quality of life things. It would be nice if the card im mousing over was drawn in front, currently I have to click and move it to see it, even if I dont necessary intend to play it. It would also be nice if you could move pinned posts, just to let the player reorganize the board as they like.
I think it would make sense to give reply cards a unique icon somewhere to distinguish them.
I wasnt a fan of starting with zero mana and only 3 cards. Felt like it makes the beginning a bit too slow.
Im a big fan of the theme you have going, and you have done a good job in having the play styles of the cards match to the personalities they represent.
I think this has high potential to be a fun game!
