Rainbow Tsunami is an endless runner with a crowd mechanic: you run through city streets dodging cars and buses, and every survivor you reach joins your crew — so what starts as one runner becomes a moving tsunami of them.
The crowd is both the goal and the liability. A bigger crew is the score, but it's also a wider target for the obstacles ahead.
Every survivor you reach joins your crew, growing the group behind you. A bigger crew scores more but is also harder to get cleanly past obstacles.
No — it's endless, scored on distance and crew size.
Yes — tap to jump. Nothing to install.
