Yes, that's fine.
We will not hesitate to ban you from the jam and it's discussion tabs permanently going forward if you repeat your worthless nit-picking from last year. People understand what the rules mean well enough, if they try to worm around them with wording technicalities then they're obviously just joining the jam to cause trouble as opposed to an actual desire to make something good, so will be banned. A 5-page essay isn't required to explain that "making your game before you're supposed to be making your game is bad actually".
