Arrow keys to move, space to attack. Avoid the red bullets. Laser Tank will unleash special moves at 10 and 5 health Try to sneak up on the laser tank before it shoots you and slice it with your sword! You can also duck bullets, but when close to the tank, its bullets are fully effective on your ducking! Think the Power Wave at 10 health is too hard? See the Mega Wave at 5.
Special thanks to EnzoExplorer for the original game! this one is fully functional with the boss with a working health, smooth movement, and ducking!
