I don't find a problem with the game resembling fallout, if he manages to develop this further into a better game all the better for us players =D Hope to see you finished game someday.
Oh and i also noticed, for some reason the ai in this version is smarter than the one in bird pax. Or it might just be the fact that a couple of the cards are just plain overpowered.
Really really liked the game, 5/5. Would have loved to play it on kong rather than the offline version for the sake of badges, but no qualms there. In fact i think the rough graphics of the game brought better emotion for the game than nicely done graphics would have.
There was a shooter game not too long ago with zombies being in the darkness called 'Zombies in the shadow'. This game sort of reminds me of that one. The difference between the two is where this one the light is "hard" and the other the light diffuses. I agree with ngrules about making escaping levels, maybe throw in some guns and make it a survivour game? But i would suggest you take a look at the game i mentioned earlier as yours looks like it might be going down the same path and that game might give you some good ideas.
