Hello!

I hope everything goes well and you will be able to submit your game in time!

However, accidents happen. If you would need to make a late submission, please contact me, it is possible on itch (but I never actually did so, so please also forgive me, it would be eventually my first time ;)

https://itch.io/updates/enhancing-jams-late-submissions-and-entry-editor#:~:text=From%20the%20submissions%20tab%20you,the%20submit%20deadline%20is%20over!

There is also a possibility to somehow "extend" the jam. The only restriction is that you have to upload a build before the deadline. If you will need then additional time to fix some bugs or add something - let me know and I will allow it (it will also be my first time, so the same as for late submissions - be armed with patience and understanding!) ;)

One additional thing - modify your submission page after the deadline - you can then add description, controls, etc. It is possible and totally encouraged, especially when you will be rushing final hours to submit your game! ;)

Best Luck!

Pawel
