If I were to add a light in my 1 bit game would that break the rules as the light creates different shades of the colors I have in game, or would that be allowed?
As far as I understand you can use transparency/alpha channel to get different shades of single color and it won't count as separate colors. However, lighting will definitely "break the rule", I don't think it will disqualify the game, but you definitely will get 1 in voting for "Does it use two colors"
