Taking elements from other media and making them work in TTRPGs is always one of my favorite things! As soon as I saw the map I was giggling over the Overcooked comparison, and I also just really dig the unique way you integrated a pseudo-montage into this. I want to run this encounter, I bet it would be so fun. At first I was a bit bummed that it was all just one minion, but I think with the amount of complexity in making the cakes, that was actually a really smart move, and it allows the heroes to designate one or two of them to focus on clearing gremlins while the rest focus on cakes. What a fun time!
