This feels like an RPG Maker Game, that had nearly unlimited budget in the art and music department.

The whole presentation, visuals and music are great.
Sadly visuals and music do not make a great game alone.
The gameplay is so overly simplistic and slow, without any trace of depth, that even the great artistic part of the game just gets old too quickly.

Let's talk about the problems:
This game has all the sins of early 2000s RPG Maker games.
What does this mean?
- Way too frequent Random Encounters pretty much everywhere (even in Boss Areas for some reason)
- Exploration barely gets you anything (there's like 4-5 meaningful gear upgrades that you can find, except for the best weapons, where 60% of them are in the final dungeon)
- One of Mechanics (Torches for dark places, get used a single time)
- Area Design that is only meant to increase the length of the game, by making you take detours
- Everything in this game is either fighting or walking
- Fighting System that could have depth but never gives you tools, nor gets creative with them.
-> We are talking every character getting a high resource high damage attack, elemental attacks are mostly the same, as in cost 2 deal elemental damage of type x. There's just nothing special to them at all. It's basicly just deal damage and if low heal. A simple script could "play" this game.
- Enemy placement of story encounters is... incredibly horrible. The final dungeon legit features 5 fights back to back against the same enemy type. No increase in difficulty or other mechanics. It's legit the same mob 5 times in a row.
- Mandatory Escape Sequence, but given it's grid based movement (on the cards) it's not using time, it's using a turn limit.
-> These Maps are completely empty to walk through with no real urgency, and just spams random encounters at you.

Aside from those there's an overarching problem with the whole game:
it's soooooo slow.
Given the artistic focus that everything is a card, everything is animated and takes ages.
The animations are great to look at per se but if you see them every single time you wanna do something they get old very quickly.
The Game also has incredibly convoluted menus you have to navigate through.
Wanna flee a battle? Press a hotkey (esc on keyboard) then aknowledge you wanna flee then throw dice (even when the attempt is a guaranteed success), aknowledge again and press through 2 sets of text. Only for another encounter after taking a single step (if you are unlucky).

Now given the game advertises with Yoko Taro, what about the story?:
Worldbuilding and characters are great, sometimes the usual crazy as expected.
However the main story is incredibly predictable and lame. Nothing really happens all game until you're at the final boss.
The game is also divided into multiple chapters... each chapter has a small recap cutscene after you beat it. Sounds cool and all... But some of these chapters are like 5 minutes long. And the story in them fits on a single bookpage.
Imagine reading a book and every new page is a new chapter and said chapter spends half it's page recaping the previous page/chapter.

To conclude this review:
Voice of Cards: The Isle Dragon Roars has the major flaw of being so mediocre and slow in it's gameplay, that even design, atmosphere and music can't make it work.
This games biggest flaw is simply being boring.
And if a game is boring... don't play it.

The art style drew me in, the funny dialogues made me stay.

This was a nice short jrpg with an interesting mechanic. My only complaint is that the plot is weak.
