This sounds interesting, though unlike [@Natsucooldude] I haven't really got much of a character concept, though the idea of some kind of "food scientist" chef Rainicorn would be fun, out to find new flavours ("Can happiness be a flavour?"), applying scientific rigour to help answer the burning culinary questions that plague the land ("Can ice cream be enjoyed by Flame People?") and so on.

Looking forward to seeing the mechanics you're coming up with for the game!
