GoatUp is an arcade platform game for iOS devices developed by Jeff Minter and Ivan Zorzin of Llamasoft and published via the Apple App Store. It is the first platform game ever produced by Llamasoft, and although it has drawn comparison with other successful iOS games such as Doodle Jump, Icy Tower, and Heads Will Roll, Jeff has stated that its main influence was an Atari VCS game called Man Goes Down and that it makes reference to various platformers of the pre-Super Mario Brothers era.
