not bad, for a stop motion....

Just a couple of things, neither Spider-Man (that's right Spider-Man, not Spiderman, he's a super-hero, not a Jew (nothing against Jews)) nor the Thing are X-Men. The Thing is a member of the Fantastic 4 and Spider-Man does his own thing, no, that is not an intentional pun. At least Spider-Man won.

The stop motion is well done and the moves were well articulated.

Someone else did it first

hmmm... This game was better when Bill did it. I don't know why you copied it, but your lack of originality is why I gave you a zero. The original game by Bill (there is a series) can be found here http://www.newgrounds.com/port al/view.php?id=7004
On a more direct line, there were no real options, because there was only one correct path, multiple paths/endings would have made it better.
