8-4 Play listeners might have already heard the big reveal that Alec Holowka and Derek Yu's acclaimed indie game Aquaria is coming to the iPad, but here's the first footage for the underwater fantasy exploration title ("part Super Metroid, part Ecco the Dolphin") running on the tablet.

Adam 'Atomic' Saltsman's studio Semi Secret (Canabalt, Wurdle) will publish the title this fall, and the two developers are also working with Andrew Church, who ported a homebrew version of the 2007 Independent Games Festival grand prize winner to PSP, for the iPad release.

Some Aquaria additions for this tablet edition include a new touch-based control setup, changes designed to make the game more approachable to casuals, minimap enhancements, and "a new layer of polish and a number of other improvements over the original game."
