Cleared without spending a dime

Ever since my two accounts both got first place in Sky City, and second place was far behind by computers, I knew this was a single-player game. If they release a comparative ranking system, it'll be troublesome. Releasing a save system is simple and won't overheat. Alright, I'll play it like I played the single-player game 'Yu-Gi-Oh! Duel Monsters' when I was a kid. Solo leveling Dragon Knight Wizard. Azcaban won't be released, I think it's because they can't rationalize the immense power of Fire Wizard and Dragon Knight Wizard. One fire breath deals over 10,000 damage, and I haven't even maxed them out yet and they already deal 9,000 damage. This game is good as a single-player game. 1. The screen is huge, 2. The crystal music is pleasant. No need to compare spending, just play slowly by yourself. Dragon Knight Wizard and Fire Wizard are the obstacles to rationalizing anything stronger, solo them.
