We did some wacky stuff to make the Unity <-> Ink inventory system in Cake King's Rent Fiesta work. Latter part of the file is pretty repetitive (probably a chance to use Ink functions better?), but still might be interesting to see

Interesting!
Fun fact, Ink knots and stitches can also take parameters, so you wouldn't need to make a function, you could just have something like:
===make_food(foodname)
You make some delicious {foodname}!
You would still need to handle the tags, but that's a descision that should be made based on how you're handling the tags in your engine.
