Not really into the "look", per se. It looks very "programmer art" in the video. If you're going for a psudeo-vector look, take a look at GeoDefense/GeoSwarm. It's crisp and simple, like your look, yet there's something special about the glow and shapes (not to mention 60fps). Cool looking game. Looks like it could be pretty fun to play.
It actually is a lot of fun to play, and has silky smooth framerate, much more than the video (I don't think that the new look will add lag, it has to be a recording issue). I like the new look, and the grid above all, makes everything clearer. Looking forward for the update. Keep up the good work.
