I'll get into the major issue I have with the game: I NEVER knew where to go or what to do. That might be a skill issue on my part, simce the game does say for example "conquer Raeve Keep", but I simply don't know where that is or how to get there. That would also be less of an issue if you weren't on a timer.
My first playthrough ended after I failed to even see Raeve Keep, triggering a game over. My second ended because I found no way to conquer/ally myself with the capital. The 'hint' the game gave me was "everything is quiet, I could probably focus on finding more about the twins!", which wasn't helpful to me.
The art is quite nice and (most) of the story is acceptable. It does devolve into meaningless name-dropping sometimes, but it wasn't too annoying. The gameplay boils down to watching a scene, exploring and interacting with towns, villages and mines on the map, and then going back to the twins. You're on a timer, so you're supposed to do the tasks they assign to you quickly, lest you want to face a game over.
The characters are kinda static, as in, they don't change that much during the story or between different choices. This is compounded by the fact that advancing the scenes/path for each character takes a long while, since you can only do so once per day after a number of explorations.
My last criticism is one that might not be easily fixable: the mobile ui is TINY. Switching savefile pages is borderline impossible because of it.
Anyway, if anyone's interested in a slower, more story focused game, this one isn't bad. However I'd probably use a guide if you're interested in a specific path.
