Hey sprvlln, sorry you were unable to submit.  This would be easier to fix had you joined the jam, because itch makes it very difficult to allow late subs otherwise.  All the information was displayed correctly on the jam page, however we have decided to extend the deadline just for you.  In the future, know that it is each participants responsibility to ensure they have the correct due date.  Things that would help to do this:

1. Visit the jam page at least once.
2. Enter the jam by clicking the “join jam” button.
3. Make note of the due date listed there as it is highly likely that the time zone is different than your own given that the internet is a big place :).

Also, we are unable to play your game currently as it fails to load and just hangs on the load screen.  And, in the future, it would serve you well to be more kind and mature in dealing with issues like these.
