The mechanic is clever, however I don't like the theme. What I mean by that is that during the course of the game the environment around you (hexes) deteriorates only. From nice green whatever it becomes more and more broken and then fall off though the floor. I find it depressing. The balance as is usual for games is a fine line. In the beginning your harvesters matter as per turn income is low. In the end game though, the harvesters are obsolete, as you per turn income is far more than a few harvesters would give you (leave alone the fact that there is not much to harvest by the end game). So when you start off you have to be extra-destructive to get an edge. I would probably be less averse if the number of tiles you own mattered, but it seems that it does not. If you are the last to survive and you own just a single tile you still won.
The pace of the game feels a bit like holdem - when blinds rise in the end there is suddenly too much money in the game - same as with greed corp - accelerates the game so it can end sooner.
