Clearly the best strategy is to beef up your resources, then send as many guys as possible at one time, and if you have a card that makes one new warrior spawn every time someone dies, the game starts to run slowly because there are about 200 guys on the map... Good concept, but definitely some improvements to be made.
When you're zoomed in, you should be able to actively scroll, say with the arrow keys for example. Also an undo button would be nice, and maybe be able to hold shift and always draw straight lines? Just a thought.
So there is an NPC in one of the weapons shops, who says that you can buy anything in this shop, except sex. The comment really isn't that important, what is important is that he is blocking access to a chest, which is the only chest I have not opened in the game...
