Cool game!
I've got a few gripes on the assistant system though. First of all, the names really should be editable. The unknown color that may go completely against the name is a bit annoying. Also, since the locations tab is where I check my ingredient stock and as such, where I decide me and my assitants will go next, it'd be really useful if I didn't have to go to a different tab to assign the assitant's routes. A drag and drop feature would go hard. Also, more info on how many ingredients I should be expecting gathered should be given for each assistant.
More automisation should also, even if not given immediately, be had. Stuff such as auto-rituals and location sorting based on lowest material stocks (This one escpecially. Probably even a thing that is given immediately. I know I would have loved it). Otherwise, to maximise efficiency (a thing my mind is cursed to do), it require quite a bit of checking between different tabs, carefully checking prices, stocks, and assistant routes. All that stuff taking up a bunch of my time, when the most fun part is definitely blowing up some fields.
A bit less important but when fulfilling an order, the next order shown should be the one directly below that one, not the one at the top. Also it seems that when spending money in different tabs, the exclamation for each tab does not update. e.g: I have 300 gold, and one of the least expensive spell upgrade is 210g, but instead I buy my third assisstant. The spell tab exclamation mark does not go away, as it should because I would then be entirely broke.
Additionnally, now this is quite specific, but the lingering touch passive doesn't specify the current amount of days added, unlike the rest of the passives that specify their current bonus. Also, the order of ritual effects should follow the order of rituals in the ritual tab for ease of recasting.
Oh and maybe remove the brew time in the potion tab. It smells of a cut feature that wasn't entirely scrubbed. Also, I got a new level after the game ended... and it gave me 'new' potions? Seems a bit weird, especially if one of the previous comments of regiving potions is true, since I was meant to have already unlocked everything. Should give a message like 'Nothing to see here' instead
A bit saddening that the middle was so orginization intensive, leaving me feel a bit like I was doing a chore so I could finally get to the fun part, but the end where I was God of Destruction, lush in my spoils of war and destroying fields with explosions, lightining and floating orbs was pretty fun.
