I have to agree with Translanka - the story seems so far-fetched (even though we haven't heard it, the screenshots speak for themselves) that I myself would have trouble playing it. The beat-em-up aspect is cool, but the fact that Link, Samurai Jack, and Trunks (Translanka, you DB-n00b) are involved seems completely.. retarded, for lack of a better word.
Nonetheless, let me know when you release a demo or the full game.
