It's a pretty unbalanced game.
It requires more luck and grinding than your personal skill: you can't move on without maximizing your character skills, which is impossible without replaying the same level (the current one, because you simply can't replay others without losing ALL your progress).
The difficulty can change drastically between levels and doesn't really reflect your effort or the stage of the story.
The visuals are good but I'm not interested in "cartoons" if the gameplay doesn't cling.
