No, not the math kind of add. I mean you can add different questions and answers to this project. Press "q" to get the little game thing that I've already programmed. Now remix and make up your own! Q-Start pre-programmed game. Space-clear all drawings.
This still a work in progress, and if you compare this to my other projects, this is much more complicated then I usually do. So give me a while to finish! :D
