I designed a whole game assuming that the user was not sleeping on the keyboard, for a simple non critical project, knowing that the button is pressed for a certain amount of time have alwas seemed enough for me

but you re right if the program is susceptible to recheck the button state just a little time ago, you should find a solution ( i had a simple delay but now that you tell me that , i believe i made the wrong choice)
