I loved it.
The story was simplistic yet incredibly enjoyable. The minimalistic textured style was also very pleasing too the eyes. I only wish you would've made better use of actual animation. Things were sometimes no more than 2 frames long, and the fight between himself and the alien could have been much more epic. at the same time, it fits the style to keep things fairly straightforward though...Hence the 9. I look forward to more of your work :).
