My biggest problem with this game is that all the fun stopped once I realized the dried mushroom strategy. The best fun is had, when you are new and are trying to survive your first winter. But once that problem is solved, the game doesn't throw any more problems to solve and is basically playing itself from that moment on.

You need to fix THIS first, rather than adding more content that doesn't really add anything to the post game, and the post game starts basically after you survived your first winter, which happens rather quickly, like 2-4th attempt.
