Thank you. I don’t think any theoretical knowledge is really required for a game like this. Children playing with paints learn the effects of mixing colors intuitively. I do understand the impulse to complement colors with numbers—I’ve done that in other games myself—but past feedback taught me that some players find the extra information distracting. They actually perform better with colors alone. Something to do with the whole “right brain, left brain” idea.
Anyway, thank you for playing, and thank you for the feedback.
