The Spirit Engine is a 2D, sidescrolling adventure/RPG game with a simple story and a straightforward, innovative real-time combat system. Written as an experimental reaction to old 16bit console RPGs, it took a little under two years to complete and was released in November 2003 as freeware under Natomic.

A plot spanning five distinct worlds. Three strangers going about their daily business, find themselves transported and stuck together on a remote island with a small, mute and ghostly spirit. They soon find themselves playing Survivor for real, trying to figure out what they should do as unfriendly creatures, bounty hunters and sinister forces chase them across the world, from misty, haunted forests and snowy mountain-tops to arid, magic soaked sand-dunes and skyscrapers.
