That was an amazing RPG.
Now, to get down to the details, this was like an old RPG that was on a site that I forgot the name of, but it was gundam wing, except the gundam one was more like a chess game. I like this style better. For a trailer this was an awesome game, the only problems, though, are common for trailers. One point is, it is much too short, I enjoyed it thuroughly while it lasted. A second is, those two moves get old and boring after awhile, although it may seem hard, I would suggest adding somewhat of a final fantasy 7 style system to it, so you can add more moves than just what the two weapons have, although it is a unique idea having each weapon have a different attack sequence, I think it would be better the way I stated before. I like how you used the Paragonx9 song defcon zero, and another one which I can't name right now for battle sequences. I could see this game going places in the future, I hope the actual game lives up to how awesome the trailer was!

-P.S. : In the new game do we start over from scratch or do we keep the stuff that we already have in this game?
