Praise: Good concept, Good menu design, solid interface, Good art, and it's fun, too. The essentials are all good.
Problems:
1) Increase in difficulty is a bit random. I have been on day 22 and 4 people and a turret were enough to defend the safehouse, and I have been on day 8 and even with 8 people defending the safehouse, 5 of which were armed, the danger still said "100%". I was overrun and I have no idea what I could have done to avoid it.
2) Electricity isn't being used correctly. If I build a turret it required the electricity to build it, but doesn't add it to the used electricity until AFTER the turret is destroyed in an attack. So I end up with electricity used that I can never get back. I've seen this happen somewhat with rooms, too. I'll have destroyed all my rooms and I still have 15 electricity in use.
3) I have to build all the rooms in the order they are on the menu. Honestly, I don't want to build a factory first every time, and an entertainment room is much less important to me than a kitchen. I might want to build a kitchen first because I have a politician and he's recruited 5 people and they're hard to feed. Food is more important than traps, and I should be able to build rooms in any order as long as one isn't necessary for the other, like a factory for a generator room, for example. (As a side note, I'd change factory to workshop. The name fits better, unless you really are making these items from metal ingots.)
