Hi ramro!

Just move around each level and avoid everything (except for the power ups of course) the longer you can keep your tail intact, the higher your score will be. When you power your tail up with the blades power up, you can slice through the seekers (the baddies that stick to your tail).

Those two things will get you the badges, but you might have to play for a few levels to slice all 5 seekers. They don’t show up again until later on in the game.
