I just love the art style. How did you create it like that, made from scratch, or did you adapt existing imagery? It looks mighty fine.
I would definitely make the video more clear as to what the game is about. I thought it was about street brawling, like some sort of Street Fighter game only with limited fighting. It did give the idea of depth, with dialogue and all. But I mean, give us more details as to the goal of the game, stuff to be excited about, show us some more mechanics or action! Definitely add some more explanatory text/lines with that.
The 'Rocky' vibe theme is also a nice touch. Your game is probably still a WIP, I think you've got the game covered, just don't let up on the marketing! Good luck!
