Is the space level supposed to be impossible to complete? If so, funny idea, but it should probably be more obvious because I was stuck there trying to figure out what I'm doing wrong :P fun game otherwise
The space level has two correct answers. Either everything is significant or nothing is. So pressing all squares is correct and pressing none is correct :) (unless you mean the one, where you see the earth. In that case, all 3 squares of the earth is correct)
