A downloadable game for Windows, macOS, and Linux

Help a Plesiosaur and her offspring navigate the pixelated waterways of the Mesozoic in this quirky, overhead-view platformless platformer. For one or two-players.

For the best experience, players should use a gamepad. You may also use your keyboard (or the combination of a keyboard and a gamepad.)

By default, the control sticks will direct your plesiosaurs through the water. Keyboard-users can exploit the WASD cluster to move the mother plesiosaur, or the nav cluster to move the juvenile. The shoulder buttons (or spacebar/return key) will make the plesiosaurs jump. To dive, press the rear triggers (or shift keys.)

These controls may be reconfigured, from the game menu at startup.

You will be presented with a new objective at the beginning of each level.

Bonus Tip: If you are about to run out of time, you can restart a level, to give it another go.
