Very good story and progression, the scenes are just still frames, and any animations are just 2-3 still frames played quickly, but the characters have their personalities and unique looks, which out weights any negative
The number of frames for the animations has been steadily increasing. It was about four or five initially. Then it went up to twelve, then twenty four and now it's about eighty frames each for the latest ones. You've got to get near the end of the current content to see the newest animations though. I may go back and update a few older ones at some point.
