Get More Plasm:

To get more "Plasm" points from each kill, get in as many 
consecutive hits as possible. The more consecutive hits you 
get, the more damage you do and the more plasm you get from 
each kill... which essentially means more powerups faster!

Kill enemies faster:
--------------------
When fighting an enemy switch to sword mode and walk up to 
an enemy and press o. when they go up in the air wait till 
they come low enough for you to hit them the press o again 
this one more time and this time when the come down do a 
shining sword (press square) to finish them off fast.
