Robo is a WIP game intended to provide a full Sandbox feel, while providing an engaging and interesting storyline as a platformer as a sort of different feel to the genre. Robo has been in development a small amount of time. Because of this, only much of the back end of the programming has been done; it has to be implemented and made to run smoothly.
There will be many ores in Robo, with around 20 planned such as the typical Iron, Gold, Tin, Copper, etc., as well as other deposits such as Sodium and Lithium salts, Platinum, Lead, Uranium, Zinc and Cobalt.
