Great stuff. I enjoyed the use of resources and how things were balanced. Visually, a great experience as well, as the constantly growing buildings make it fun to keep progressing.
However, one small issue, and this might be a problem with my underpowered laptop, but once I reach about brew level 40 or so, not all of the resources being collected by my NPCs/buildings were actually being registered in the game logic. Workers on the salt mine would keep harvesting substance, but several in a row would simply not register before suddenly they'd begin registering again. It wasn't only the salt mines, as each resource began experiencing this issue with whether or not they'd register fluctuating throughout.
Even still, it was very fun to play. When possible, I'll test it again on my Windows 10 gaming rig to see if it was specifically an issue with playing it on a browser on underpowered hardware. I'm running Firefox on Linux, and everything else worked great!
Only other recommendation would be a way to review previously displayed tutorial messages, as I had to restart my run due to accidentally clicking through an important tutorial message about the morel farms.
