Cool. The demo has pretty much done its job. I just hope the grinding is at least rather more rewarding in the main game, and the Cerberus has a huge hp pool, am still getting whipped by the harpy, which is annoying enough, due in part to a slightly janky camera position when fleeing.
The plot feels flimsy, and the Italian opera'ish music is lovely.
Online also works really well, you still get stuff even if you sacrifice, which is nice.
