Good premise, but some flaws
This game had a pretty good premise, but there were a few little things that dragged it down. I really hated the second boss, because he continuously stacked that instant stun move on me and I could only break out when he let me. Allies were more or less useless. Most of the time they wouldn't even take an action, just stand around while enemies destroyed me.
The game was getting to rather cheap levels of frustration at that point until I got the final two Animal Powers.
I don't know about the other classes, but the last two animal skills make you a god. No fight, regardless of the number of enemies, lasted very long once I got them. Marbleskin stopped me from taking damage, and stacking Beastman and Lion-Force meant that I never missed, no matter how fast the enemies were, and struck for over 100 damage and one shattered piece of equipment every attack. The last fight was actually ridiculously easy doing this, because I couldn't be touched.
A few things that could be done. Allow for more freedom in who and what you fight, instead of dragging us along to each set one. Allowing us to fight the boss when we want, or go on fighting other fights, would be better. I'd also try to give more customization of what your character looks like at creation, instead of giving everyone the same bodytype with different tints.
