Nifty idea, fun... just a few thoughts.
The storyline is terrible. Pretty much anything would be better than "new planets being born at an incredible speed". Where are the material that's creating them come from? I suggest an evil magical monkey casting "magic expanding planets" at you, instead. More plausable.
Next, why are the turret colors reversed? If it was my ship, I'd send someone out to repaint them ASAP so they matched the planets they were supposed to shoot. And then I'd shoot his ass for painting them the wrong colors to begin with.
Also, it would be nice (perhaps as an "easy" option) to use left-hand buttons (say, A and D) for shooting instead of the up and down arrows.
Left the door open for a sequel with more turrets and colors. Good thinking!
Overall, yeah, fun.
Quite fun, i like it
Did a great work, amusing game.
fun and addictive nice work!
This game has pretty good visuals and a very interesting flow. The various other obstacles like asteroids and sabotages keep the game from being repetitive.
