You've improved
Yup, it seems your flash movies are getting better as time passed. You already put out 4 submissions but I still haven't even finish my first one :(
But there are rooms for improvement:
-put some sound effects or music (although not exactly necessary in this short flash) into the flash
-some more storyline into the flash?
Well since this was made in 4 hours you're doing fine already within the time limit.
