'Twas okay.
You've still got a long way to go. What I see here is an average sprite movie, not too good, not too bad. It's pretty good for a first flash, though, since most don't get any further than a five second animation of a stick figure. The humor was okay, the sprites were okay, however, the animation seemed very laggish. Try to make it flow a bit more by adding spoken dialogue and not leaving the introduction screen displayed for, what, ten seconds or so? It doesn't matter if it becomes a bit shorter because of this, because the quality increases. Quality over quantity, always. Also, when you include drawings you made yourself, spend a little more time on them; see which colour fits best with other colours and so on. Alright first attempt, keep them coming.
