Totally didn't see that one. Disqualified!
Too bad. The rules are rather explicit about the dimension limits, and I have no other choice but to respect them else I risk a mutiny of 4k programmers "Hey, he could break the rules, why not me?!", and nobody wants that

Should have published sooner for the feedback

No need to panic, yet! I think everyone deserve a chance to fix minor errors, as long as the game itself isn't changed. So, if you want you can try to squeeze your game into a dimension that fits. Might be difficult though, especially as it's already hard to read what it says on the balls. Anyway, there's your chance (1-2 days from now).
