Um... not so bad but...
I'd say it's a little too boring. First of all I thought you used only samples from the game... that was kinda disappointing... Second - what's with the reverb? Its waaaay too much. Third - the beat is a little to loud. You can't hear the melody very well, which in my opinion is very important. Kinda no diversity as well. Nevertheless it's original. That's why I'm giving it 3 (I hesitated if I should give you 4, since I'm a big worms fan but 4 out of five for this is a little too much, I think)
