Thank you so much for such a detailed feedback, and for giving my game a good try!
I'm sorry that you couldn't win once. I wanted to add a lot more weak cards in the game to create a proper weakling opponent, one it's almost impossible to lose against, but I didn't have the time to design more than about 20 cards. As a result, the number of weak cards didn't leave me enough cards to create a proper weak deck. You're right about the accessibility, my next challenge is to present and explain the game more efficiently, and optimize the layout and readability.
Thanks for the compliment about the game design! I let it simmer in my head while I was implementing basic duel mechanics and AI, so there was a lot of time to think about it but it caused a lot of late adjustments, too. And I'm glad you liked the art, I honestly wasn't confident about that part at all, especially when as you said there was so much of it to draw, and this is by far my weak spot. I'm the type who can't even draw a straight line, but I decided to fully capitalize on that visually.
I'll try to keep the updates coming at least monthly, thanks again for your valuable input!
