Dear Developer, please use the money from my purchase to get a decent translation from fiverr. To the rest of you, I can't recommend this game in its current state. The graphics are beautiful and the battle system is intuitive (although most fights usually laughably easy and it quickly gets repetitive), but the translation is so bad it is nearly unplayable. None of the menus make any sense and the story is completely lost.

Okay, the game was very a refreshing and moving experience for an offline JRPG. The graphics and animation as well as the gameplay was a nice touch. Hoping that more chapters will be added and story to be finished because this game has superb potential to be awesome. And yes I finished the last story chapter which was to defeat Aydin and the unexpected mystery corridors.

Bad translation, no voice acting in any language, the guy in the team looks like a girl(especially his face), short and unfinished story(it wasn't bad though, until it abruptly ended), lots of grind required to get stronger, hard to obtain even the most basic crafting materials. Two stars is the most I can give this game, and that's for the sheer amount of effort taken to make it look presentable and the ok-ish combat system, though counter timing for dodging is very tight.
