well yeah, but am I not forced to use Blacknd White only? Considering the theme?
Viewing post in How does Black and White need to be
To reiterate,
"The main condition is to create a game that uses any two colors."
You're allowed to use any colours you want, as long as you're still only using 2. Black and white will probably be what most people do (especially considering the theme), but you won't get counted off for doing purple and black if you so choose.
