Crash Landed - Concept Art - Miscellaneous
Gloves and Dingodile
These were made in 2008, back when ideas were still being thrown around and the game had no clear shape yet. This image seems to be the oldest revealed concept for the game, and it doesn't resemble anything in it at all.
The proposed gloves here would lend Crash special abilities. For example, the Mitts of Lifting would allow Crash to move heavy objects, whereas the Spider gloves would shoot webs, and the Digger gloves... well, those are pretty self-explanatory. The glove concept was abandoned in favor of the game's item combination system.
The same picture also shows a drastically different Dingodile that was quickly shelved. While Dingodile was set to appear in the game, he looked faithful to his usual self.
