I never played your first game, so I can only comment on what I know of this one. It seems like you've nailed the basics of a space shooter game, thats for sure. I liked the general animation fluidity and the usage of sound effects. However, some thing to work on are the overlapping movement patterns, a more definitive death sequence, and a more progressive battle sequence. At this point you're kind of thrown into it with nothing more to accomplish. I think you have potential as a designer, you just need to spend more time working on and improving your concepts.
