It's good to hear from you again! Sadly, there is no burping in this game. It does, however, contain a lot of other great features that I hope you'll enjoy :) like weight gaining, eating, force feeding, etc
I do but it's a ghost-town. There's no one on it except for me 🥲 when I was developing Fatrifice, I made a Discord to see if anyone would join but so far no one has lol. If you want to be the first to join, here's the link. I'm not very active on it, though, unless more people join!
