Thank you for the feedback.
Regarding the palette, the rules provided in my language state that you can create your own palette.
“Você também deve ser capaz de usar a paleta fornecida - você pode até mesmo criar a sua própria!” means: You should also be able to use the provided palette—you can even create your own!
If the color palette was grounds for disqualification, then the games that came before me for evaluation should also be disqualified because of their controls.
