I know that most of people cant submit ace of coders, but i got an idea which works:
if you go into a level that can submit like this:
You go and move your pointer to the submit part:
It says “Ctrl+Shift+Enter. Run in real time” it means to submit, so go to ace of coders and do “Ctrl+Shift+Enter”(i dont know if this works to mac or others, it works for windows tho)
hope this works to you!
