Yep new to this jam business - so I have a game called Miami Life which I intend to gently use to poke humourously at a well known eighties tv series, anyway, anyway its currently built and on Itch and you can fly lots of vehicles and drive boats and all that but it is lacking a communication system so my aim is in a couple of short days to have you able to interact textually with characters although maybe just one character to start with but  i'll try and get two in - thing is the build that has no communication system is on itch now,  when I stick the new build as the itch download how do I prove its new?  like if I submit it here then say yeah, yeah I just put the text system in, and the old build that didn't have it is gone how is anyone going to know I worked on it?

I deleted some of your post because it was inappropriate.

Itch shows when games were uploaded and when they were last updated, which is how people submit older games they have worked on during the jam, which is allowed. However submitting games that have been submitted to a bunch of other jams is not allowed - please read the rules before submitting.

You can also use a devlog to log updates you make.

Great explanation, cheers!
