Like others have said, there's an upgrade bug that needs to be fixed. After a certain point of upgrading, whenever you click an upgrade the game ignores it and next rounds continues. Ok game otherwise, a bit of grinding at the start and repetitive later.
One new bug appeared...mage spells sometimes don't work when using it (eg. use mass heal but hp is not healed). Not sure if this is also the case for other classes.
Wish there was an option to automatically assign people to scout the whole map. This way I don't have to keep clicking the same scouter over and over again. Otherwise, this sequel has much improvements, good job!
Very nice soundtrack that fits the game very well. One complaint that I have is some of the places where spiders hang from are unfair because you can't see them until you jump up, but by then they have already dropped on you. 5/5 for sure though.
Though auriplane already provided a completed map, I made one more concise which I believe is easier to use: http://img190.imageshack.us/img190/687/snailiadmap.jpg
