Suggestions for ideas? I've got one or two that might be worth a spin.
First idea - beating a horror by solely giving it food it loves will gift you a new permanent recipe, one that will be useful or loved much more down the line. (I'm thinking maybe 2-3 areas ahead so it's not spammed/abused)
Second idea - Same as above, but the giant horror for each area not only gives you a permanent recipe, it also gives you a permanent piece of gear. The downisde is, you have to return back to the castle to equip it, instead of equipping it immediately.
Possible final idea - Horrors have a chance to recognise the princess, immmediately halting their progression and allowing you to fill them up and yourself.
