The first thing about the game, is the art is really incredible! This is not just the dragon and the heroes, but everything from the backgrounds to the card art. The game has a lot of character, and I especially liked the text on the cards. The music was also a really nice touch as well!
I had a minor bug where the game wouldn't display properly on my monitor so I had to change my monitor resolution to see the whole screen, but it worked great other than that! I think it's a really solid game, and even more impressive that it was made in just a week!
