Varuna is a standalone flip-and-write game that features the same graphic style and is set in the same universe as the publisher's earlier games Ganymede and Demeter.

As a scientist, you just boarded a ship departing from Ganymede to Varuna, an oceanic moon.

The goal of the game is to score the most MP (Mission Points). These points represent your ability to discover and to study the dinosaurs in their oceanic environment.
