I miss the open world
There really isn’t an open world to speak of. You unlock characters as you go along chapters but it’s a linear progression of unlocking characters and cards as you go along the story. It’s also a little jarring to use a character you’ve unlocked then replay a chapter where you previously don’t have access to said character. Kinda... weird. It’s minor but it’s really not for me. The card battle mechanics are pretty solid though.
