OH NO MATH!!!!!!!!!!!!!!!!! Okay well, it's just addition. Difficulty influences the range of numbers that could be in a question. Once you've chosen a difficulty, you have 60 seconds to solve as many addition questions as you can. A right answer earns one score point, a wrong answer takes away one score point. At the end, your performance will be shown: score, and amount of correct/wrong answers. You can play again from there! This project's art direction is so weirdly Frutiger Aero-inspired. I don't even know why I went there.
