penguin-man, that wasn't blood on the metroid's madibles, that was part of the metroid. It was obviously made from the orginal metroid1 sprite. And yes, it was supposed to be on the inside of the large claws.
The only thing I didn't like about this was that samus didn't fight back. She didn't even freeze the first one in her sights. she just ran and blew the planet up.
but it was still a good idea.
