Looked very cool!
However it reminded me more of say the original zedla made of Legos. Like, if I were playing with legos to recreate the game.
Awesome. I would so buy that.
I would recommend changing the style to be super stylized if you've got the time. You certainly don't need to, your visuals work fine and are VERY decent (with good art direction for the levels, they'd be great. And art direction does not require polygons), as in I would be happy to play such a game. But it injects a freshness into the game, and can put you on even grounds with big name developers without the budget or hardware. Also, there is so much room to be creative like. that Not like Bushido, that is great, but works only in 2D as I'm sure you know. You'd need grey scale, or be really clever about it. Like the characters could be silhouettes if they were clearly defines but their guns were bright colors, then the landscape could just be black outlines, and maybe white or red fill or something. hmm. It would be really cool if the fill could changed. Also, if characters were silhouettes, showing their health would be super easy, as you could have the color of the character be the health, like black full, red of something dead. Would still be different than Bushido, but close. There are so many ways you could go, stylized just means you're created a very distinct feel with the visuals or experience as a whole, though it's most used if the feel is really radical and loud in one direction. Quiet Stylized things don't get called stylized as much...
Just a stream of thought, up there for grabs. I know what hell it is to game something look great in DBC, and it's not much better in DBP. If you're interested, I can throw some ideas at you for style, or some sketches for art design. But you did very good with Bushido, not sure you need the help. If when you get back into this you're interested, let me know.
