I'm perfectly happy with the work you've provided so far and hope you'd be willing to continue providing additional assets. There are still plenty of structures that need to be replaced, all of the robots, some 'glamour shots' of the structures for the built-in help / revised interface (eye candy, basically) and all of the robots (miner, digger, dozer, explorer and truck). Not sure if there will be a need for any additional robot visuals.
Would be nice to get research icons but that's kind of a stretch goal. I wasn't planning on using the original visuals for that anyway.
And again, very much appreciate all of your effort! It's helped to move the project forward and give it a refined edge.
