My potato can't run this but I already have some few gripes; not with the game, but the translation, as I did play the prequel.
I feel like Roots shouldn't be plural, since it refers to the original world, the ROOT of the three new worlds.
Sol was referred to as an ancient witch, which is completely wrong. Sol are humans that have fused with a Magic Orb, granting them immense powers. They are the ones who saved the original world from destruction and created three new worlds for the humans, demons, and gods. There are also only two Sols currently: Ely, an ancient Sol from the first game, and Rui, the newly awakened and extremely talented Sol.
Also, I hope Rui beats the crap out of tentacle man, because her Sol powers are extremely strong. In fact, she is capable of defeating entire races.
