Use space for the arm attack, use the arrow keys to change facing direction, use down arrow for shield, and use the "b" key to activate Ultra PrisimX (Ultra PrisimX can only use its proper space key attack).
This is just a little program I made while I was bored :) ---------------------------------------------------------------------------------------------------- PrisimX is a monster in Mega Monster Mash who is intelligent enough to know the difference between good and evil.PrisimX's powers are to control photons (since he is the god of light in Mega Monster Mash) to create illusions, but usually uses his arms in a fight. When touching Werignaconite he can transform into the most ultimate creature of all time: Ultra PrisimX. PrisimX's greate st feats are chopping a dimension in half and escaping a black hole.
