I played with a human rogue and recorded it, then a fairy rogue, fairy warrior and human assassin off-screen. Video:
I like the idea! Dominion but in a roguelike way. Dominion is an excellent game I think the way you are aiming towards making it a single player video game is very interesting.I know it is a very early version of the game, but the cards are way too small on the screen. Even in fullscreen I had to go very close to my screen to read them. Also a lot of the times I was hovering over a card, clicked it and another card was selected. I noticed the undo function later on from the menu, but there should be a way to "confirm" that a card is going to be used in such a way that it doesn't disrupt the flow of the game too much.
Difficulty is a bit wonky. I managed to win with the warrior though it was a struggle. Meanwhile rogue was too difficult and I haven't found a good strategy yet. Off camera I played assassin and that was a breeze, you have everything at your disposal with +action, +card, trashing, card duplication, a lot of damage for cheap and even healing on top that cycles.
I hope you develope this game further, since it has the foundation for something really fun.
