Good stuff, but in 2 of 2 tries the rocket was destroyed by the flying asteroids, so basically not much fun.
Maybe make rocket indestructible.
There is difficulty slider coming up.The shield bubble takes 10 hits and can be recharged with atomic icons, also defending the rocket with lazers is highly recommended.
New version is up.Shield is now 25 from 10.Shield regen from atomic pickup is now 5 from 1.
Enjoy ;)
