Same as everyone else, I'm afraid - it's unplayable. The fact I'm giving you 3 stars should be an indicator of how much potential there is here and how good this game could be.
Put simply, it's far too hard. I sent a team away to scavenge and recruit, suddenly a raid was upon me, and there was no way I could get anyone back in time. Game Over, simple as that. That's brutally unfair, and in no way related to my skill as a player.
Other items don't explain themselves. Recruiting missions are a success, but the icon remains over the buildings? So what, can I recruit again? Apparently not. Scrap seems a generic cash-based material that isn't particularly interesting. How much food does a survivor eat? Why can't I build those rooms? What resources are more important? You fail to explain any of this.
Of course, there are also horrible bugs, which need to be ironed out. Simple mechanics of the game don't work. It seems just a little rushed, and it's upsetting because this game could be absolutely fantastic with just a little work.
Go play Rebuild, one of my all-time favourites (or preferably the sequel), and go see what makes that game so great - it's not unfair, you just sometimes have to risk things for greater reward. Implement the best features of that game into here, and this could be a classic. Just don't punish the player just because you think that makes the game fun and challenging.
