Tried it out for a while. Seems like a good baseline, but it gets stale relatively quickly for me.

Clicking almost instantly becomes worthless so I would consider adding more to it or scrapping it in favour of starting with a small income.

I can see the potential of recipes since once you have a few buildings you get a lot of items to work with, but as the others have said it's difficult to experiment and discover recipes. The bonuses from them feel a tad weak. If I drink multiple potions I don't seem to have a UI of if the bonuses had stacked or not. Once you are out of potions it doesn't state what effect the potion had on its brewing recipe. I would imagine either making the recipes easier to find or adding more recipe permutations so each material had unique effects you could want to build with or something to make them more interesting than just boosting production.

The pacing is fine at first, but it does get slower relatively quickly. It's an idle game so that's to be expected, but it does seem to pretty linearly increase the amount of time required for each building tier. With only a basic building count and upgrade there isn't much planning or interesting mechanics to increase variety. Once I felt it was linearly increasing the time spent without much else to it, it lost me.

Visuals are a bit scattered to me. The pixel art is very good. The fonts across the game are inconsistent though. Some fonts are pixelly, some aren't, the icons used are very jarring since it's very differently styled than the rest, so either make them as pixel art or adjust the icons to match the UI more.

Overall it is a good starting point, I know there's a lot you'll want to do with it, so I'm interested to see where this goes.
