You may love the leveling system now. Give it time. The flaws will start to stand out pretty quickly.

While the concept is cool, the execution fails. Mostly because it will not keep your stats well rounded. As you Dodge more attacks, your Dodge increases. Which makes you Dodge even more. So eventually you have really high evade. But this means that your defenses are pitiful, so when you do inevitably get hit, you have no HP or Defense to make it survivable, and you get one-hit-killed.

Magic is absolutely ridiculous at high levels, because not only do you have to keep using it to level it up, you have to use it a particular number of times in each battle to continue to increase it, and very few mobs will live that long.

Due to the way so many of the different systems work against each other, you have to grind a ton to get everything up and keep your characters fairly viable. And the best way to grind? Hitting yourself. Expect to spend hours just sitting around beating up your own characters as you try to get through things.

And, as the final nail in the coffin, the dungeon design is not strong. There are tons of pointless mazes that don't feel like actual locations, and are incredibly easy to get lost in. You get no sense of where you should go, or why the location is structured the way it is. And if you ever save in a dungeon and put the game down for a week, good luck. You will probably never make it out of that dungeon when you pick it back up.
