So simple, just click right or wrong can be.
But each question only two seconds of reaction time, wrong answer or did not answer are deemed to fail

So freaky
Looking within the stipulated time how many questions you can answer, though wrong, the answer can continue, but there is time to punish ~

So easy, so freaky and so fun!
