Comment:
It was a nice game... I don't like it as much as the other two, I think you added some really cool additions (Hunting, runes, etc..) but it feels like you tried to push the focus away from the essence that the other two games had. I also really don't like how I can't use all of the special weapons because I picked one faction, or one aspect of that faction (ie, I can't use the Ultimate Villain's weapon because I chose range for the Sun Faction).
Bug:
You can go through and hunt everything twice if you don't accept the missions. In more detail, as the camps appear you can go to them (without accepting the mission from the Hunter) and defeat the enemies. Then when you finish killing them all, you can go to the Hunter and accept all of the missions.
Bug:
Not sure if really a bug, but when I was fighting the Holy Dragon and the Dark Dragon I stacked up melee fighters on their front and then wanted to avoid damage so I went to his back and started hitting him, he then froze and took our damage without doing anything.
The logical leads and conclusions for objects needs to be more clear. Also items need to be a little bit more obvious. Didn't even realize I could look above the vent even after clicking around the room several hundred times.
One of the better tower defense games I have ever seen. I like the graphics and I like the game so far, obviously this is just the beta test version; but you definitely need to throw in things like:
