I really like this sort of game, and the jam didn't produce many like it. Shame that it's so buggy...
It's a pretty simple game, but that's not necessarily a bad thing in a jam context. If it wasn't for the bugs, it would be easy to just hop in, figure out how the game works, and try to save (part of) the world.
One thing I'm not sure if it's intentional or not: You don't seem to be able reassign people you've sent to collect wood. I'm curious what the reason for that is.
