If you mean the game with the two muscular men.
You shoot sparkles, continuesly.
Pushing foward and sparkles, usually will trigger the head beams, which can be done over and over. I do not know the limit.
While pushing fowards you can make the attack go in a tilted direction,
slighlty. Depends on which direction you push in.
Then you can also dodge all attacks, but I believe this eats up your time
meter. The objective of the game is to go threw the stage, without using
almost to no special, otherwise the time will get eaten.
Like that Super Famicom Game "Island game, whatever it is called " the final enemy ( or is the second to final enemy??? ), attack is undodgeable, and while you can manuver, you need to move fast.
I do not know if you can speed up, a bit,
Also you can take control of two players at one time.
