Kobo II is a fast paced physics based dual stick arena shooter that intends to bring the frantic retro arcade gameplay of the prequel Kobo Deluxe to old and new players alike, while offering a much smoother and more sophisticated experience.
Mostly internals this time, though there is now "all-to-all" physics going on (that turned out to be quite a bit of work), and background collisions have been enabled. The enemies are not yet particularly skilled at navigating through the terrain, but at least they're trying to not just crash into the first wall they find. Oh, and something weird has happened to the title screen starfield. :-)
