Click the green flag to start. You will have 10 seconds to memorize the numbers. The numbers will disappear. You will be asked questions about the numbers. Answer as correctly as you can. There is exactly one correct answer per question. Writing the numbers down is considered cheating, but I can't stop you. The test will be terminated upon the first incorrect answer, at which point you will be shown your score. Good luck.
I would like to give credit to superscratchnerd42 for the sprites. I would like to give credit to _yobro_ for the music.
