This is like Asteroids meets Geometry Wars, but with bosses to fight on occasion.
You can use either full DPad and buttons, or a combo of touchscreen and DPad (or buttons.....depending on which hand you write with) to play ala Geometry Wars.
Hardest thing to get used to in this game is that when you move your ship, it keeps floating like Asteroids instead of the tighter control of Geometry Wars, so you die a lot because of floating into stuff. Backgrounds can make obstacles hard to see....stuff tends to blend into the background.
Still, it scratches my old-school itch and plays fairly well for what it is. I like it.
To be honest, I expected a heck of a lot more of these types of games on the DS. Wish there WERE more of these types.
Guess I should add the obligatory; Works on CycloDS B.4.
