Anyway I've finished what's been released so far. I felt that chapter 10 ended up dragging on too long and became exhausting (though it doesn't seem very changed from the previous release). I think this is because you're pretty much backed into a corner by all the reinforcements coming in, and the remainder of the chapter involves taking a lot of turns to get through the rest of the map in order to fight Rashka.
However, after that i feel the quality increased for the following chapters. It felt like pretty much all of the characters in Gid's story had their purpose and ended up turning out well for me (at least from the few chapters that were available). The ending of chapter 13 definitely has me intrigued to continue the rest of the story when it's available.
In Ragnar's tale I feel that Donwik is a bit too slow and doesn't have the def stats to justify his usage. In fact, Vidar seems to fufill that role already in addition to having better movement and use of swords (plus he ended up with better speed and def as well). Also, I think Kai got screwed for me because he didn't start gaining speed level ups until very later on (Kiowa turned out to be much better for me).
In contrast to Donwik, the female armour knight Philomena felt like a great improvement over him and an armour knight i actually wanted to use.
Anyway, that's my critique so far.
