Amazing art, first of all. 13px is a killa. I love that the guys make little campfires when they're neglected, however I found it a little frustrating trying to 'gather them all up' since they often want to stay behind. The flag waving animation is kino. The little comments they make are great, very Kingdom Rush. Love the bowling pin sfx. The terrain code is great, all angular like that. It looks like some of the swamps are even curved. It looks like the buildings cigarette health bars are actually just a series of images, because as I'm watching the health decline, they seem to be different lengths, which is kind of amateurish. Just render them with code and procedurally draw a rectangle that gets redder the shorter it is, then they can be smooth instead of going in 'chunks'. The right mouse button could do something, maybe 'rally all troops to this point' or something. Also a hud would be nice. This could be a real big boy game making money on steam with a little polishing.
