So I beat the very first boss about a dozen times now and once I do, I can neither submit my code nor access the multiplayer; every time I try to join, I have to do the tutorial again. Apparently I am not the first one this has happened to today.
Every button on the lower right is greyed out and deactivated once I beat the boss by adjusting the speed. I get the (presumably) last panel of the tutorial with “You are now ready to move on to better things” (something to that effect, I did it in french.) But then, nothing, as mentioned it won’t let me submit nor test again and it doesn’t take me to another webpage on its own.
