Surprisingly great RPG. I loved pretty much everything about it: artstyle, music, UI, battle system, difficulty (the game is great on hard mode) and writing (loved the characters and the dialog).
The game does have a few minor drawbacks though. Losing a party member usually means you either have to restart the game or revive them immediately, because otherwise you get stuck with a bunch of cards you can't use. But it's not a big deal.
The best part about the combat is mix and matching party members using combos (which you absolutely need to do if you play hard mode). Theis leads to interesting combat situations like for example, Galeo is supposed to be your healer, and Copernica your wizard. But by using combos you can actually heal more effectively using Copernica after a certain point in the game (I'm talking about AoE heals, Galeo is still the best when it comes to status ailments and regen stuff) if you do a combo with Galeo in your party.
Orik is also quite fun to use and he has easily the best combat animations in the game, I love it.
The game lasted me for about ~30 hours or so (should be less if you play on normal, probably), which is honestly a positive. So many RPGs out there that stretch the play time with so much filler you don't even finish them in the end.
My only complaint is honestly the final boss, I thought it was too easy compared to the challenge that was the rest of the game, it was a bit anticlimactic. But still, had a great time with it and hopefully there's a sequel (or some DLC) in the works.
