I love your prototype, this and https://pacoball.itch.io/pacoball-dragonball-rpg PacoBall were my inspiration to create something similar, but totally different.
I love the representation of the battles, it reminds me the nes card games, and the open world, it's a great idea !!
And you solved very well the lack of some sprites, like Raditz in The Legend.
I'll follow the development closely, good work!
