This game is written pretty well. Fort has powers as a summoner genie but he has to fight an evil empire. However, the writing excels because it puts twists on cliches, such as the resistance not being trustworthy neither. However, the gameplay in dungeons is terrible. You will backtrack out of dungeons by casting the teleport spell because it is faster to take 1 fork and re-enter the dungeon from the nearest town than to waste time/money backtracking even with the holy bell to prevent encounters. The difficulty is challenging but impossible if you abused the holy bell; bosses will spam spells to cripple/kill your party by hitting everyone at once and you need to be faster and have protection by having a higher level. The strategy remains to attack the minions first and take out the main boss last. The class system is ok but flawed, though Fort is really the only person in your party with a personality. In short, you choose from 4 classes and can upgrade via gold cards you can get by finding a cave of trials and beating the boss (who you need to be a few dungeons ahead to win), or by in-app purchase (the defeated monster currency for elite items is only affordable near endgame for 3 leclear ores, since the ultima chain to prevent status effects is only 1 and costs the same). Class changes put you in level 1 stats but with prior skills, which is a letdown. The thief is also useless because you can't steal good items against bosses and buying safety boots for the godawful amount of traveling on spikes/lava makes the safe step skill worthless). There is some customization by gender, hair/clothing color and race of your monsters, but the upgraded classes are exactly the same (blader/knight/warlock/priest) for any prior class; Fort should have had an upgraded summoner class because he can't catch up unless he uses a gold card. This game has potential but the broken dungeon design (nearly forced iap's if you minimize backtracking) and cheap bosses make it only worth playing if you don't mind backtracking. I would not bother buying the bonus dungeons because they are probably just as broken with overpowered bosses who can change everyone's status conditions in one move, backtracking and damage floors.
