This game is wonderful.
I can really feel the inspiration from games like A Dark Room, which is one of my all time favourite games.
You've taken that concept and bumped it up to 11. All round a great experience.
I'm probably in the minority when I say that I don't believe this game needs a proper tutorial like some are suggesting, but maybe a little more direction in terms of what's happening as you play. E.g, the fire brightening as you place buildings could be more obvious, locations not being accessible until they were in sufficient light could be more apparent etc.
Outside of that, thank you for this experience, it was lovely and I hope to see more like this from you in the future.
