Like a blue hedgehog!
Deceiving death itself
Button 2 is more useful now
One after the other!
Babies make you tougher
You're gonna love 'em
Copying enemy movements
A new challenger appears!
He lost his drill for...
He also wants to hit
Gotta shoot fast
It gets spiky
Helps hitting your target
You're feeling tough
At last you can watch it
I'm gonna catch you!
Your actions are under control
Take me seriously!
Speed up!
As if it wasn't hard enough
REAL blue hedgehog!
Thank you for playing!
You're the real champion!
