Really hard past a certain point – Block Fortress Review

I was playing on easy survival and had a pretty good house and $2 worth of rare minerals in turrets, but I couldn't get past the night where the cloaked guys come out, it's really hard, and I've tried several methods to complete it. Every previous wave was relatively easy but this one was seemingly impossible with my layout. It was really fun but not worth my precious $2, because there's not really an objective or story other then to survive long, and money and minerals aren't easy to get when it costs to receive, and your spending money on defending yourself anyways.
