Well, the game is actualy pretty good, despite the translation being about half or maybe two thirds of the content at the current build (0.95), is enough to actualy enjoy the game and understand the story.
The developer did a good job in making the game not so grindy (you have to repite optional scenes 2 or 3 times to get the full scene), and since the game IS linear you can advance despite not knowing the lenguage(the maze are well done and not so hard to pass) , also the scenes talk by themselves sometimes, so you can get what´s happening almost all the time (trough since secondary content is not fully translated yet you may end up losing some good scenes or side-stories, so i suggest to explore every map at several story intervals)
Now lets talk about the story, you play as a nation-wide famous thief, who wants to get enough money to retire and live a happy married life, and in order to reach that goal you explore tombs and ruins, infiltrate in castles and treasuries, and get in asociation with criminals across the nation, that the basic premise of the game.
Overal the game is enjoyable and fun to play, and once you experience the first and second map you´ll naturaly start searching for events, which in turns means you most likely wont get lost too many times, and if you actualy get lost it will be easy to get on track by talking to some random npc or trigering some random event, trough some times i wish there to be a walktrought.
