All good, I didn't think it was your intention to try to disqualify me or anything. I guess the organizers understand that minor mistakes are made and that they are unintentional. In fact, I went to check the main page of the jam about it and the "Any examples of 1-BIT games?" link points at a list of games and the very first game that got #1 of that 1-bit jam has antialiasing text! LOL.

Also if you think about it, the splash screen is also part of the game, it can be disabled but some people forgot to do it, and any godot or unity game that has the splash screen should be disqualified, since Godot uses blue, black and white at the same time and unity logo has different shades of grey (and antialiasing!) but I don't think anyone will be disqualified on those technicalities if the spirit of your game is 1-bit.
I don't want to fix it now because I want to be fair and not update the game until the voting period ends but I'll look into it as soon as I can. Thanks!
