MUCH improved.
Okay dude, another step in the right direction. Only two real suggestions left on my end. Storyline, and some more enemies (try for a few origional creations. :) Even if the graphics aren't TERRIBLY awesome for your own artwork, a touch of personalization would probably kick it all up a notch and have peeps thinking 'Ooooo...that's different'
In either case, NICE work. Playable, entertaining, and overall a better experience.
Thumbs-up. :)
