how long can you play?

rules are as simple as the game is pointless, hence the placement in this category.
as you opened up this page, the timer started its countdown.
initially you got 30 seconds.
at the same time, the game timer started.
as you press one of the three buttons, your countdown timer is either unaffected, gains or looses time, depending on the random value the button is currently hiding.
you can only press the buttons once in 5 seconds. dare you wait that long?
try to play as long as possible.
oh, and yes, if you took longer than 30 seconds to read the instructions, you just lost your first game! but no worries, you can always restart it to play again!
good luck!
let’s play!
countdown timer: 30 seconds
game timer: 0 seconds
enjoy!

disclaimer: i am aware of the unlogic in loosing with 29 seconds played by doing nothing, given that you have thirty seconds to start with. although not planned, i’ve accepted the time-warp-factor of this programming and will not spend more time trying to understand, change or correct it.
