As usual, really appreciate your feedback :)
The broken item should be chocolate which was removed from the game in an earlier fix, we already realized we missed some spots.
As for balancing: can't really argue with you there, it's not something we spent too much time on when trying to get the game to a releasable state. This goes for alle balancing related stuff you mentioned, the trees, worker costs, drop rates and so on.
The workers getting stuck part made me kinda curious, maybe we'll look into that someday.
We're still glad that our little project got people interested enough to email or comment us about it. And all jokes aside: we already decided that IF we ever get our next project to a point where we have something to show (since all this is done in sadly really spare spare time), you're one of the first to know ;)
Super light spoiler: your assumption about your progress in the game is about right, there's not really much left.
Kind regards,
CodeDude
