The game is good! It has a pretty goos story with a small twist at the end. There is some minor grinding but nothing serious! It feels like the pokemon games without pokemona!
The characters and storyline are cute and such, but the gameplay is an RNG nightmare that revels in wasting your time. I cannot, in good faith, recommend this game to someone who isn't a HUGE fan of orange_juice's works.
After you win, don't your cards get the same XP? Does only the card that won get XP?
