good.
I liked some of the scenes especially with the metroid.
There were only a few sprites used though, there could have been more for a fluent movement etc.
I liked how you made Samus love fighter that was pretty random.
However the music that was used seemed to continue after the credits and i tested this by replaying and the Riley music was still playing despite starting again, if you were to attempt more flash then I would suggest fixing these problems first.
