you can, the site doesn't block you, but it's considered cheating and overall a little unfair and rude, even thought this farmer bug is as stupid as 1 line of code

I believe it's acceptable to update to fix issues like this... see the thread here: https://itch.io/jam/game-off-2020/topic/1090193/can-i-edit-the-game-if-i-submit-...
Yea, I know that but It's against my principles, I prefer to show what I was able to do. Stupid bugs I did because of stress and crunch is not something I'd like to hide from myself because otherwise it would lose stake and I would give up efforts to be careful about them the next time. In real commercial release settings, day 1 bugs can be a pain.
