Hey! That's really sweet that you showed your friends, and I'm glad you all enjoyed it so much!
When you say you'd like to see what ingredient types can replace each other, do you mean inventory categories/filters? Currently, if you click on an item, it tells you the item's category at the top.
Since the game jam closed, I've been working on updates to the balancing, adding new recipes, and adding a "grocery run" system, where you can, for example, spend $5 to get a random kind of cheese if you're only missing that. In play tests, it's felt really good, but I have to wait until the jam ends to update the itch page. If you check on my profile next Friday, I think you'll be pleasantly surprised by how much better at feels- and I'll continue working on it throughout the week (top priority now is just adding more ingredients/recipes and maybe some more upgrades)
I appreciate your detailed feedback, and my wife will be really happy to hear how much you enjoyed the art :)
