DarkIce Mines, the first SpellStone area in Star Fox Adventures, was another area that was more complex in design in earlier iterations of the game than in comparison to the final release. The leaked December 2000 build of Dinosaur Planet showed that the lower underground mines portion of DarkIce Mines was meant to have an extra set of puzzle rooms on the right side of the map that would wound up connecting back to the waterfall room. These extra areas were also present in the E3 2002 kiosk for Star Fox Adventures, suggesting that they were very late cuts, very likely as the development team was being crunched to get the game out in time of the Microsoft buyout in late 2002, similar to what happened with Dragon Rock.
