(hello, i'm a new guy here)
(I coincidentally got an account on these forums Right before i dsicovered this story by unrelated means)
(the animations are amazing! all those details probably take forever. one of the parts I remember and liked was the star-background effect when the vessel of grief used its scythe)
(...granted, i probably noticed that the most because that was one of the few parts I saw with a really slow internet, so it player .5 - 2 FPS cuz it had to load the next frame, which makes it way easier to see all the cool details on the attacks)
(my only qualm as far as general how-the-adventure-is-made is that there are some parts of the animations for attacks or actions that I think would be really amazing to see slower and i can't really do that)
(which more or less translates to "my problem is you do it too well I can't even see all the awesome" : P)
[don't have anysuggestions right now that haven't been said, though i might think of something, who knows : )]
EDIT: Yes to the thing above, I animate things semi-regularly, and 5 seconds can take a day or 2 without Any backgrounds and with everything a stick figure of uniform texture.
as i read once somewhere, 'first rule of animating: Animating Is Hard.'
