Great game <3. There could be a desciption of how the sprinklers work when you are buying them and I hope the cave gets updated to let you get iron or place a shortcut to the lower levels once you get there. In the mechanics store you could sell only ores to the player and make them pay an extra cost to use a smelter in the store (or in the blacksmith), so that if the player gets any ore in the caves he can go to the store to smelt it and make the sprinklers; it can discourage the players of saving to get a smelter, but if the price to smelt is afordable yet expensive they will still try to get a smelter to make more of a profit (there could also be items the player can craft using metals for selling to encourage building a smelter), and also, if the player has to either save up a fortune for the smelter or use a week's profit to get a single copper sprinkler it will discourage farming or make it letargic until you have the snowball rolling. Thanks for reading.
