Very interesting unique game. I don't really get why you went with a sci-fi setting combined with an old school book though, seems like clashing themes but perhaps you have an idea for it. Combat seemed a bit weird to me, most of the fights ran out of time because I couldn't do damage fast enough and if you don't get enough attack cards it seems like there's nothing you can do about it. At first I expected your deck to get shuffled when you've exhausted it, but the combat just ends for some reason. The combat can definitely work if you tweak it I think though.
Spelling error on pg. 57, but it was the only one I noticed so that's good.
