A short, beautiful tragedy, with a very simple yet fun gameplay loop.
Took us 10 hours to finish, at Level 50, while opting into every boss on Hard.
(Word of advice: on top of completing all 3 quests in each area, grind each area for all Critical Books as well. And only bother upgrading your 1st & 3rd skills)
Also it's free, so just give it a chance.
