Skill levels
The higher the level a skill is, the more powerful its effects will be. When viewing a card, the current skill level and the amount of exp required to level up the skill is shown. The menu to level up skills can be reached by tapping on the "スキルアップ" button. In this new menu, skill up scores, fragments of feelings, and pure crystals of feelings can be consumed to provide exp towards leveling up a skill.
