Hello.(I maked this program.)
if you want attack to virus,then you need Press L or R Button.
if you want kill virus,then please Press L or R button Faster.
"HP"is virus Power. if virus power is 0, then you killed virus.
but virus is angry. if you rate click,then PORTIM OS was crash.
this Virus is very Strong.(my think)be careful! and good luck!:)
