Very cool concept, with tons of potential. Reminds me a bit of a streamlined Neo Scavenger. Like Daniel I also appreciated the hill/visibility mechanic, but I wish there was more to see on the map, like some indication of what might be found in a given hex. Seemed a little too random /luck-based whether you might find what you need.
But this is a terrific platform to build on, and I could see it becoming a really good game. (Art is cool too!)
