Seen this every now and then for 4 years and honestly the story never gets old. Doesn't matter the graphics, sprites, or art. You have an amazing story and imagination. Honestly though my only complaint is you did not present a prologue to this ending.. it just left too many questions.
I know you had ideas for a season 4, but still; I'm not asking that anything related to the plot be given away, just a little bit of short term closure for at least a few of the hero's such as GC, Zetto, and of course, Alpha. (Maybe a little bit of personality added to Motherboard as well? - Not much for only knowing her as literally a goddess who went berserk from being treated like garbage by a virus.)
Any case, your newest TOME series is awesome and can't wait to see more. Take care.
