Goat Up 2 (lost deleted iOS game, 2013)
From The Lost Media Wiki
Goat Up 2 was a secret to Goat Up developed by Llamasoft. It was a platformer game in which you play as a goat, collecting items around the stage and consuming them to fart, extending your jumps or damaging enemies. It featured a level editor with the ability to export and import levels to be manually shared.
The game was released exclusively for iOS some time in March 2013 and received favorable reviews from EuroGamer, Edge Online, and Indie Statik. At some point, presumably in 2017 when apple removed support for 32 bit apps from iOS, it was removed from the App Store.
