Complaints:
The deck menu is completely broken when trying to manage any deck other than the first. Try it and you'll see what I mean.
The three damage types need something to differentiate them from each other.
I don't like that all the fragments in the first area have only untyped attacks. Not sure what the solution is to this.
If you hit the arrows with the weak attacks the game crashes.
Replaying the first story section sucks because you can't skip the opening cutscene, and if you want to refight the mysterious fragment you have to fight the first boss as well.
