SPOILER:
The second half of the game is impossible, since everything purchased in the first half works against you and there's no upgrades available to help in the new direction. Restarting the game does not reset the point total, which must be brought to zero to win and is likely in the thousands by this point.
This is either a reasonably well crafted albeit unnuanced statement about the ecological hazards of mineral extraction, or unbalanced and buggy.
