This release retains the basic gameplay of the original version, but has technically more advanced graphics and sounds, as well as a few gameplay-related tweaks. New areas have been added to the game world, and the game has now a free-roaming camera.
Originally released as one of the few 64DD (the Japan-only rewritable expansion to the N64) games. The Gamecube version includes new graphics but removes several features including an expansion pack that allowed to play as a different character.
The name Doshin is a modified onomatopoeia for the sound of the giants feet striking the earth.
