it had its bad points, and its... bad points...
okay. so i congratulate you on your working button. good job. you did say this was a test, so i'm not going to get too critical here.
i'm already sure you know the obvious points:
it's not much on content
drawings could've been better
some animating could've been smoother (i.e. when he first begins to fall. check that out, and fix the jumpy part)
and the good stuff:
the button works obviously
the music was a good choice
i like the way he hit. it didn't actually show it, but it not-showed it in a good way. i like the style of that scene
keep it up. in future submissions, add more class, and more content. you know you can do it.
