Llamasoft founder Jeff Minter has revealed that the studio was forced to abandon development for iOS after the platform proved to be unsustainable.
The Space Giraffe, Tempest 2000 and Gridrunner creator said on the dev'sblog: We spent two years doing games on iOS and in the end we stopped doing them because the income generated from them was so tiny that it ended up actually costing us money.
Despite excellent reviews both by users and on relevant gaming websites, and notwithstanding the sheer number of iOS devices out there which would, you might think, make it viable for even stuff slightly off mainstream to find enough of an audience to comfortably sustain them, this proved not to be the case and we couldn't in any way justify carrying on with it.”
Llamasoft's first iOS title Minotaur Rescue was released in 2011 and followed by other games including GoatUp, Super Ox Wars and a Gridrunner spin-off. The developer's latest mobile effort was 2013 sequel GoatUp 2.
