hehe - thanks for the feedback
The game is supposed to be vicious, but regarding the spawners, they are easily dispatched of if you lock your facing direction (X) and strafe at the waves of drones and spawner. You don't *have* to duke it out hardcore style like the guy playing Robotz DX on the youtube video.
Actually, that guy really shows how the game should be played; strategically and with quick attack decisions.
From the readme:
"Always take cover after releasing a volley of shots at an enemy so that they cannot retaliate just before they are destroyed."
