Public Matches Are Part Of The Steam Description
The official Steam description says Meccha Chameleon supports public matches and that people you do not know can join when a server is not set to private.
Recommended Player Count
Steam currently says 2-10 players are recommended, with the final maximum depending on the host network environment and future playtests.
Private Versus Public Servers
For friends-only sessions, keep the server private. For public or viewer participation games, check lobby settings carefully before sharing or opening the room.
Best Planning Advice
If your group is near the upper limit, use a stable host connection, confirm everyone is on the same supported platform, and test one match before committing to a long session.
