What does that mean? What is the theme, cause I don't understand what you mean by "do it yourself". Does that mean I made that robot game for nothing cause it didn't match the theme? I didn't even know there was gonna be a theme.

Update: Oh, Do it yourself meant DIY... I knew that...

Well, more or less, yes, you did it for nothing. Because on this main page of this game jam was written since the creation of it that the theme for this game jam will be announced on monday. (even though I think it was announced on tuesday, that doesn't matter) You should have waited until the theme was announced and then decide what game will you make based upon the given theme.
