A vast game by a single developer.
This game has a LOT of mechanics. From the core one (collecting humans) to stealing totems, to upgrading, to kicking the other player :D All these mechanics come into play, but I do feel they feel a bit "glued together". Perhaps it is the map size (which in my opinion is way too big) that it feels like you can do everything but need to do nothing. I did play it with the AI, so a lot of the criticism is aimed at the AI (I believe that splitscreen mode is much better).
I did miss some silly music to give my ears a break from the pretty annoying step sound. Other than that it felt empty from time to time (probably still map size). The gameplay loop though is fun and with minor tweaks this can be a very good game with friends.
Good job!
