Qoute from the creator (AKA Derek yu)
Aquaria is by far the most ambitious game Iíve ever worked on. A massive underwater fantasy game that features hand-painted graphics, a beautiful soundtrack, and professional voice acting! Action, adventure, romance - the game also touches on a number of deeper themes, including religion and the idea of creativity, and belonging. Alec Holowka and I spent two years making it, and it has taken us places we never would have imagined, not the least of which was the award stage at the 2007 Game Developerís Conference, where I got to properly thank my family and friends for all the support theyíve given me!
