Pretty cool. I loved the movement rule, the art is great, and the rules in general seem light but encompassing enough. Also, the layout make it very easy to read and understand, and the examples are helpful. Aguante.
There are a few spelling mistakes, though :p . But that's OK. Argentinians don't know how to speak Spanish anyway :p .
Just kidding, of course. All in all, a nice game.
A few points: Although it is pretty obvious which skill's related to which ability, clarification wouldn't hurt. Also, I didn't really get the categories (why is First Aid in People?). Maybe it would be easier if the skills were categorized under their relevant attribute; you know: Muscle - Hand to Hand, etc - Agility - Rifles, etc.
The Competitions between Characters section is a little confusing, I would advice to stick with one of the methods. The first one seem the most logical, even if it goes against the normal resolution.
An Index would be very helpful, though maybe this is a little anal of me considering it is a preview.
I hope this is helpful and not annoying. If it's not, then I'm sorry.
So, I look forward to see the final product. Vamo arriba.
