Rough around the edges
Music and sounds are fine. For a starting point it's not so bad overall. The animation is what needs the most work. It looks too rough to for me to discern any sort of style. It would look better if the characters could move more than their eyes and mouths.
After the X-14's show up the frame rate goes to shit until the replay button shows up at the end. Changing the quality does not help. If no one else runs into this problem then it's just my PC being diffucult. Otherwise, there may be something offscreen that's hogging system resources.
Also, why is he climbing a mountain?
