The concept of this sounds neat; I couldn't really find to much to do at the moment though.
I like the art and music a lot and the idea of two people from backgrounds completely alien to one another trying to communicate to solve their problems is a solid one. I get the feeling this is in -very- early stages at the moment though.
Once I got out in the rover, it took me a long time to find the first part to stop. Any sort of visual indication here is better than nothing, strapped for time or not. I placed a radio tower, but I couldn't figure out what to do after that.
Side note - if you return to the base, it re-triggers the opening scene again.
Congrats on submitting your demo! I'd be interested in playing this again when there's more to see.
