Very cool game! Everything felt super polished. The gameplay felt very satisfying, and the reward cards were very well designed. I can see hints of possible different routes that path the way to victory, which really adds to the replay value of the game. My only suggestion would be to maybe add some juice to the game. Maybe size up the dragon just by 5-10% when hovered, and shake the screen or the crafting window a tiny bit when crafting is completed (you've already added the hammer sound, so why not?). I think these would really add great value to the overall feel. But overall, amazing game, had loads of fun!
