Nice little game. It was fun seeing all the little guys walking around doing their thing!
I got stuck for a while, where I didn't realize my two builders were killed, but I already maxed out my new buildings with lumberjacks, so I had to wait for a few to be killed so I had room :P After a few waves, most of the action takes place outside the screen, so I had no idea what was happening. But this is very understandable given the jam!
