Hi there. Lovely game. Like an earlier commenter, I'm stuck on the (final?) puzzle with the 3 vertically sliding doors where the chimney has lifted the cabin into the air. Could you provide a hint at all? The only thing that suggests a solution is the appearance of the top of the cabins from a top down view, but I can't relate that to any potential configuration of the doors.
(Also, is it the last puzzle? I accidentally closed this tab and I'm not sure if I've got it in me to brute force that window light puzzle again to find out...)
