I found this to be a pretty good game. I think I can recall the previous one. Of course, I have played so many it's difficult to keep track of them all. I thought the graphics were quite good. I like it how it appears as though you can restore your health while you are fighting an opponent. At least that was how it was with the boss.
I do think this isn't that creative. The music is good, but it doesn't seem to add anything that new. It is kind of satisfying to look at the enemy designs. I also like how you have a map that shows everything. It's not much, but it's good for what it is.
