Do I need to wait until I fully completed my game before submitting or can I submit now, so interested parties can follow the devlog and what will be judged is the state of the game after deadline? This is unclear to me, I would appreciate if somebody could explain. My project page is here: https://harebrained.itch.io/metabolize

It’s fine (and encouraged) to submit early! It’s only during the judging period that uploading things is not allowed.
