Really great proof of concept! Got some Pokemon vibes just from the general perspective, art, and movement system, good job! The controls aren't overly obvious, and I struggled to figure out how to interact with people for a minute or two lol. The card 'battle' system is pretty intuitive and easy to get the hang of, and was pretty fun overall.
I was experiencing a possible soft lock with the opponent past the bridge to the south. After winning the first round, the game prompts me to place two more cards and then stops responding, with seemingly no way to progress other than exiting the game and restarting. Despite that, I still had a great time playing this.
Overall, super impressive for the time constraint. The mechanics and art feel great. Excited to see where you take it!
