Factory Town Idle by Erik Asmussen

Factory Town Idle is a unique town builder that takes place entirely within a massive living spreadsheet. At the start, simple clicks will harvest resources, create housing & production buildings, and assign workers to craft items. You’ll choose which items to sell at the markets, and which to refine into better items. But as you gain experience, you’ll acquire tools that help automatically manage your growing town.
Eventually you will gain the ability to expand into exotic biomes, unlocking valuable resources & recipes exclusive to those regions. All along, you’ll need to invest your earnings back into research and upgrades so that your town can earn you increasingly large piles of coins – even while you’re away from the game!
