Found a bug: When you die and press continue the HUD disappears.
Other than that it feels like your game has potential, but at the beginning it feels rather overwhelming. Like what do icons in the top right mean, what are magic crystals, etc. Although after playing the game for some time it becomes clearer what it all means and I didn't even make the mistake I made when playing Alderex'es game and pollute my deck with garbage cards, I dumped them at the savepoint(or at least tried to, cause the price for doing it to some of them was too high). I liked the gameplay and how some cards affect some enemies(e.g: card costs no mana to use, but there's an enemy that gets a buff every time you use a card, etc.) If this is how MtG plays I understand why MtGfags spend so much time and money on their hobby.
I don't think I have much else to say. I could point out how the style of characters and tiles is inconsistent, and how it's sometimes hard to tell which tiles are walkable and which aren't, but that's clearly due to the game being at an early stage of development.
