Hey Neebzan - thanks for reaching out! After some discussion about this rule on Discord - We've decided that updates are only allowed after the voting period of the jam is over! Itch.io will automatically lock new submissions and only make them available again after the jam is really over!
In other words, you can submit as many times as you need while the Jam is still going on but once that deadline rolls around further submissions will be locked until after voting is over!
