Aquaria is a side-scrolling action-adventure game designed by Alec Holowka and Derek Yu, who published the game in 2007 as an independent game company Bit Blot. The game follows Naija, an aquatic humanoid woman, as she explores the underwater world of Aquaria. Along her journey, she learns about the history of the world she inhabits as well as her own past. The gameplay focuses on a combination of swimming, singing, and combat, through which Naija can interact with the world. Her songs can move items, affect plants and animals, and change her physical appearance into other forms that have different abilities, like firing projectiles at hostile creatures, or passing through barriers inaccessible to her in her natural form.

Humble Bundle, Inc. is a digital storefront for video games, which grew out of its original offering of Humble Bundles, collections of games sold at a price determined by the purchaser and with a portion of the price going towards charity and the rest split between the game developers. Humble Bundle continues to offer these limited-time bundles, but have expanded to include a greater and more persistent storefront. The Humble Bundle concept was initially run by Wolfire Games in 2010, but by its second bundle, the Humble Bundle company was spun out to manage the promotion, payments, and distribution of the bundles. In October 2017, the company was acquired by Ziff Davis through its IGN Entertainment subsidiary.
