Graphics are good, but its stickfigures
Well, I've never spoken a word of Spanish in my life (I can only guess that it's Spanish) so I couldn't follow along with the story. If you could get someone to help you put an English version together that would be great.
The graphics and animation are excellent, but I rated low for style because the only thing I liked in it was the scenery, which was done well.
But stickmen are everywhere on NG - it would be great if you developed your own unique style, that's all. You've definitely got some good talent.
Overall I liked it, and it would be interesting to see what you come up with in the future.
