Hey Nano, checking in on your game!
I like the premise and idea of the game, I'm digging this kind of management style games. I understand that you have a lot of placeholders still but if the main workshop screen is the style you want to go for then I think this would work, looks pretty neat!
I've played until I got the ability to brew sleeping water (post tutorial, in a proper playthrough) but something bugged? Timer went from 0.20 to 0.60 and then I keep getting failed to brew despite using lavender and the other herb. I also had a weird bug with fullscreen mode, I went into settings, changed to windowed mode and tutorial put me into fullscreen for some reason. On top of that after tutorial ended it put me back into windowed mode like I wanted lol
Regarding tutorial, I have to say that it's slightly annoying, very handholdy, maybe a bit too much. I don't think you need to explain audio settings to anyone in tutorial, but I'll leave that up to you. But it left me with no doubts about how the game works so you succeded with that part.
There's a thin balance to strike in this game, between managing different timed things and making sure player has always something to do. First thing after tutorial - you start with no items and have to wait 1:30 for one expedition (there's a funny thing about tutorial mentioning that you don't have time for expeditions yourself, but having empty inventory, you absolutely do lol), that's crazy, I'd suggest letting player start with at least some starting items and also let me get more summons over time (i only got to level 3 so maybe there are more, i just didn't get them due to bug). I wish there was more stuff to do beside clicking things to be done and waiting, like maybe minigames you have to perform for those task to finish (example being games like potioncraft or while the iron's hot), maybe not as elaborate, but something to do. And if the player wants to auto complete those task they could maybe use summons to do it for them? Just throwing ideas.
I must say that I really like brewing for the fact that it doesn't tell you explicitly what's required for recipe, you have to research and figure it out on your own, that is cool. It needs some QoL features in UI (e.g. harvest field could change status when it's ready to water/harvest cause right now i need to click it) Idk about the font for Title texts, it's very hard to read sometimes, with funky letters like b or g
Can't think of anything more, in general I like it, I could see myself spending a day with the game, progressing further and further, tho I wonder if just getting new recipes is enough to keep me entertained for long, I feel like you're missing some paradigm shift like many incremental games do. Keep up good work Nano!
