Mutant Storm Empire -- World 2 Level 2 (Black Belt)
This level is more about survival than points. There are some good combos you can get to up your score, and they are challenging. Try to get the big boulders that roll in about halfway through the level. If you can avoid being hit, you'll get a nice bonus at the end, as in all the levels. Stick to the bottom of the screen to make it easier.
