@#$% HOLY!!!
That was so awesome. your animation technique has reached a new high. There was great music. Action. The storyline unfolded greatly here. What else can you ask of a series?
And I wonder why people would complain about buttons, unless they were excessively small. I never had problems with that, to be honest.
It might be excessive to say that this is the best animation ever, but it is definitely among perfect ones. I cannot tell you how to improve this series besides going along at this pace to complete it.
