*you hae to actiate the small buttons first -then the big ane is usable

*you see the red buttons the first moves down by pressing the first small button -i pressed the firrst third and fith button but the big button is usable if i press all 5 buttons

if i press all 5 buttons they will lose their effects until i press the big one.
if i press the big button a door get open and close and you can start the cycle again
