I can't believe someone made a "I can't believe they made that many things" game for the jam. Good idea with nice execution, with great art all around. I'm a fan of memorization games, but having to learn new recipes on the fly while customers were staring me down felt a bit stressful. I should probably just get used to it. Maybe introducing only one new ingredient per level would have helped, but that might have made the game too long for a jam submission.
This is kind of only a minor nitpick: dragging all the ingredients with the mouse was a bit wearying, but I don't know if there's any way to improve that--adding keyboard shortcuts for the ingredients would probably make it too fast. Perhaps scattering the ingredients around and behind the counter would be better; that way you'd at least be making different hand motions for all of the ingredients. You'd probably need extra art for like baskets and drawers and things...not that you didn't already make A HUNDRED unique items, goodness! An even more minor nitpick: Not being able to grab an item that's partially scrolled into view is kind of inconvenient.
Sorry I didn't mean to spend more time on nitpicks than praise, because that does not reflect the proportion of how much I actually enjoyed the game, which was a lot. Great job! Over a hundred items though! In one month!
