Hi there!
Great question - when you submit your game, you’ll be able to list up to four team members, and those are the names that will be officially credited. We definitely encourage collaboration, but we do ask teams to stay within that four-person limit for submission.
If someone leaves the team early and is replaced, that’s totally fine! Just keep in mind that only the final four submitted names will be credited, so it’s important that everyone on the team, including the team member that is leaving, is aligned and comfortable with that arrangement.
Hope that helps, and feel free to reach out if anything else comes up!
