THIS IS A MULTIPLAYER TEAM-BASED DETECTIVE GAME WHERE YOU CAN USE VOICE CHAT TO TALK TO NPCs
You can directly talk to NPCs with your voice. This is how you interact with them. Search for murals on the walls to uncover dialog lines.
Search the city for hints posters about the crystal ball location, and for murals on the walls, to learn a new mechanic about the world.
Your team must retrieve the 3 crystal balls to win. Choose a side and collect hints to locate the balls. Maybe I should have said that first, but you can speak to NPCs in this game, so shh.
Nobody is reading all of this, so I'll tell you something curious: next to the Flonkus Fountain, there is a small tower — go in and search for a moving stone. Behind it is a secret item.
