Thanks for the nice feedback and for spending the time to play and rate.
It's my bad; I've used the game over menu scene for both winning and losing conditions but forgot to update the menu title when winning ... If you get a Bravo, that means you won even though the title on the dialogue window says Game Over :(
I've also just realised that I've pushed out a version with reduced gameplay as I was testing one of the winning / loosing conditions and forgot to reset it back before publishing. It's not a breaking bug, but it makes the game very short; that's why you had the impression you didn't need to do much.
You can check the status of the system by going into the chair room and sitting on the chair; that brings up the dashboard where it says how many lanterns you have, how many are lit, what the town mood is, and where you can order more wood.
