Yes, two people can participate together in a competition (game jam) on itch.io. Here's how you can collaborate and submit your joint entry:itch.io
One person submits the game: Only one team member needs to submit the game to the jam.itch.io+3itch.io+3itch.io+3
Add your teammate as a collaborator:
Go to your game’s page and click Edit Game.
Navigate to More > Admins.
Enter your teammate’s itch.io username and click Add admin.
Once they accept, toggle the Contributor option to display their name publicly on the game page.itch.io+8itch.io+8itch.io+8itch.ioitch.io+1itch.io+1

If the jam includes a voting phase, both team members can participate in rating other entries, provided:
Each person has joined the jam individually.

This setup allows both of you to engage fully in the jam’s activities.
Unity 2022 supports multiplayer games. The easiest ways are:
Netcode for GameObjects (Unity's built-in multiplayer tool) — good for co-op games.
Photon PUN 2 (very popular, free for small games) — easier for beginners.
Mirror (open-source, powerful but a bit more manual setup).
If you and your friend both work on the same Unity project, and want multiplayer, you can:
Set up a host and client system (one hosts the game, the other joins).
Or use dedicated servers later when you’re more advanced.
You’ll also need to learn basic networking (sending player positions, syncing actions, etc.), but it’s doable, especially for small 2-player games.
