Thanks for the nice words! You're in luck, because not only do I plan on adding so many more optional things like that, I have an array of burps from some generous players who offered their work. I suspect at some point each time one happens, they will be unique! Of course my favorites will occur more than once.
There does exist such a contest (albeit short) but it and other things are for a certain tier of Patreon. At some point that will go public/into part of the game, just not sure when. Excited that you like it all!
