Was quite enjoyable and simple concept. UI was simple and worked well. I liked the art and the music and sound was really nice too. Some more variation in duels outside of time and maybe some animated elements in the background to spice and it could've made it a top tier entry. Well done.
Fonts and colours made it hard to see / read some things. I liked the hand drawn look to the art. Repeated contradicting rules seemed a bit unintuitive. Some sounds could of real amped up the atmosphere.
Great art, card play can be a bit frustrating with so many random moves. But otherwise it does the genre well and feels extremely polished for the jam time.
