My thoughts on this game :
Even with a complete and comprehensible translation it still be tough to play, because for some quests you don't get much info regarding where you should go or what you should do next. Most of it is guesswork.
Secondly, the starting can be pretty tough as well because you are pretty much underleved in comparison to the enemies you are facing, expect to 1 or 2 shotted by enemies in early game quests. But once you get to a high enough level, with better gear and get the jet flame skill for your dragon you can pretty much 1 shot all enemies in game except the bosses.
