First entry to a great series. They still had some stuff to figure out here and the cyber elf system is no the best in this game but it's still a lot of fun and the story is actually interesting.
Some of the levels are designed a bit better than the first game and the bosses are a bit better also. Still has some great music but grinding for ship parts or playing that mini game everytime did get a little annoying.
Some levels and bosses are pretty annoying and not designed well especially the one where you fly on rockets. Overall a lot of fun and some amazing music.
