Roon complaining about the party brings up an interesting detail I don't think you covered. Whose party is this, anyway? If it's Roon's, then it's kind of odd he's complaining about how boring it is. Though the fact he's said to have brought the drinks suggests it's someone else's party he has arrived at. The panther's? Oh well. Regardless of whose party it is, he sure knows how to liven it up! Also, the mouse guy is cute. Pity he's gone by the next page.

A good question, indeed!
In fact -spoiler ahead- throughout the comic I will not elaborate this any further but thats because I am heavily imfluenced by Souls-like story telling (you gotta figgure out the lore by item descriptions). XD Jokes aside.
The party was actually organizes by Quinn... Thats the white Alpaka guy in a very fancy coat. His parties are legendary on Vore Planet. He invited Roon and asked him to bring some shrinking potions along. He even (secretly) called the cops so Roon would get seriously challenged as a predator.
It was a story twist I originally intended to elaborate in the comic. I wanted to include Quinn as a cute but jet highly dangerous/unpredictable antagonist.
But as the comic was an ongoing thing that I did for my Patreons at that time, I decited to put more emphasys on including some of my Patreons as rewards (as later pages will reveal). So I cut the more lore heavy section, which would also have distracted from the smut. However as I started out with that plot at the beginning, it feels amiss later.

Ah, I was wondering about "quirky" guy. I'm surprised he's intended to be an antagonist since I didn't get that idea about him at all. He just seemed like some random comic relief type character. Though looking back at some of the things he says and does, I can kinda sorta see what you mean about him perhaps not being entirely on Roon's side. And he does seem like the kind of guy to throw a wild party and then call the cops on his own party just to make things interesting because he's "quirky."

Yeah really a shame I couldn't flesh him out more in this comic. Maybe in a future project.

Who says you can't? As far as I know, you can still reveal him as both the party's host and the guy who manipulated things to get the police called, can't you? What's preventing that from being the twist at he end? Unless you mean you still intend to do that but just don't have the time to focus on him as a character being the guy responsible for everything.
