The short answer
Drink the Ocean supports co-op for one to four players, all on desktop browsers with keyboard and mouse. The main menu lists MULTIPLAYER between New Game and Settings, and the official description says you can drink alone or with up to three friends.
What the game does not document is how a room is created, whether progress is shared, or what happens when someone disconnects. This page records those as open questions instead of filling them in.

What co-op changes about the loop
The goal is one shared ocean. If two players drink in the same world, the sea level is a single number, which means the group's slowest straw sets the pace unless everyone upgrades. That is why the upgrade pages matter more in co-op than they do alone.
A two-player recording of a full run shows both players on the same drained seabed with different character colours, which is consistent with the listing's one-to-four claim. It does not show how they were invited, so the invite flow stays unverified here.
Questions to check in the MULTIPLAYER menu
- Whether the host creates a room code, an invite link, or a public lobby.
- Whether the ocean percentage is shared or tracked per player.
- Whether a player who joins late inherits the drained sea level.
- Whether treasure is instanced per player or first come, first served.
- Whether progress survives a disconnect and a rejoin.
Multiplayer questions
Can you play Drink the Ocean with friends?
Yes. The official listing sets the mode to co-op with one to four players, and the description says you can drink alone or with up to three friends.
How do you join a friend's game?
Unverified. The main menu has a MULTIPLAYER entry, but the flow behind it was not completed in this research pass, so no step-by-step invite process is published.
Does everyone need to own the same straw?
Each player appears to carry their own straw, but whether upgrades are individual or shared was not verified in a co-op session.
