Not the best thing in the world, but I liked it. Kid Goku is awesome and those sprites are cool. Only thing I'd mention is the movement is a bit jittery, but it's not a full on animation so that's not really important.
You could make some really cool DBZ skits though.
its missing something
It doesn't hold your attention very well. There is nothing to it. I like Goku but put some more characters in it.
