Very interesting and unique concept!I struggled a bit with figuring out what to click until I realized that the next thing to press would be faster. In my head if they flickered at a rate of (10, 9, 8,7,6,5...etc) then you would have to click them like (10, 9, 8, 7,6,5... etc); Then I realized it would actually be (10, 10, 10, 10, 10...) and you just had to click the next one that would change to become fast. Very unique and verisimilitudenous!
Great story and atmosphere to fit that story too <3
