Derek Yu and Alec Holowka's Aquaria, the Super Metroid meets Ecco the Dolphin game that won the Independent Games Festival's grand prize award back in 2007 when it released for PC, is now available to buy on your iPad.

Ported by Andrew Church and published by Semisecret, this iOS release includes new touch-based controls, changes designed to make the make the game more approachable to casuals, and other enhancements and improvements.

If you never played the original, the game has you playing as Naija, "a lone underwater dweller in search of her family, as she explores the depths of Aquaria. She'll travel from hidden caves, shrouded in darkness, to beautiful, sunlit oases."

Along the way, you can use Naija's singing ability to "create your own music, affect nearby creatures, move pieces of the environment and even transform Naija into different beings" while investigating the remnants of ruined civilizations.

You can download it now from the App Store for $4.99.
