Invasion of the Ivson 1: Oddpie is an abandoned Keen 1 mod by mortimer. It involves Vortikids who create robots and clones of Keen to steal the hero's newest invention, the Supersonic Pie. Three versions were released in late October 2009. The latest one features 16 new levels and custom graphics, but no patching or edited texts. The mod was nearly finished with a new world map and patches, but that version has been lost. The author stated in 2011 that he doesn't plan to finish his early work.
