Good first movie
After reading your 'about me' it's good to know you were willing to actualy put effort into your first movie, very big kudos for that. The movie itself was good, nice job of replicating the Worms experiance, with a touch of Halo.
Now for the bad stuff, the animation and action was really slow paced, even morso than the real Worms. Try things like incresing the frame rate, it'll make the animation smoother. The sound quality was too high, this made the file size waaaay too big, try lowering the sound quality in publish settings, it'll cut the size nearly in half. Also the BG music just stopped halfway through the movie, then started you should fix that, it kills the atmosphere.
But that aside, good job! Keep up the good work!
