Pretty awesome concept. Boils down solo adventuring into one bite-sized package. Can easily see how it can be modified. Already have a Mandalorian style sci-fi epic in my head.
Glad you are enjoying it! My goal was really to do just as you stated; boil down a solo adventure for easy pick up and play.
I'll have a template, after release of the finished game, for people to create their own adventures with. The aim will easy modifiable rules, so you could throw together a sci-fi fantasy game, including space travel!
