What is OCTO?
OCTO is a 3D story game where you play the only octopus in the sea who can use tools. The fish have no arms, so you open clams, unlock treasure chests and free neighbors trapped in nets.
At first everyone is grateful. But a gift only you have soon turns into envy. Swim from the Coral Garden through the Kelp Forest, the Shipwreck and the Deep Canyon to the Sea Palace, and see how the village treats you in the end.
What do I do?
Follow the goal pill and arrow at the top of the screen. Swim up to a villager and press E (Grab on a phone) to talk and get a request.
- Pearls: open clams to get them. Put pearls in a gate's sockets to open the way to the next area.
- Treasure chests: locked chests wait in the Kelp Forest and the Shipwreck.
- Ink: press Q to squirt ink and escape danger. Eat shrimp to refill it.
- Hearts: lose all three and it's game over; you restart from the last save jar.
- Village mood: the fish face bar fills from yellow to red as the story turns.
