Use arrow keys to move. There is 3 different kinds of balls: black= you, red= tagger, and blue=healer. The tagger freezes you, the healer unfreezes you and gives you 1 HP, and there is npcs of you on the field that can also be tagged by the tagger and healed by the healer. You start out with 50 HP, lose 5 HP's every time you get touched by the tagger. You are the guy in the middle bottom of the screen. If you are frozen for an amount of seconds, you get unfrozen. Can you stay alive forever?
