A big improvement over the original in every way. Zwei's gameplay is smoother with faster shots, smoother movement and a better camera. The areas are more visually interesting and the music is great. The story is still pretty simple but it's much better than the first one and easier to follow and care about as well. It's also cool how they incorporate some ground sections for variety. The difficulty feels more fair in this one though the last couple levels can be a pain to get through in one go. Also the final boss fight is awesome. Sega just can't stop pumping out the soul.
