Ok, so I played through as much as I could of the normal route of this version, and here's my feedback and what I found.
First, some minor things.
1. I noticed that whenever I would autofill Brooke's equipment while she was wearing the Chubby Chaser item and was inflated or waterlogged, she wouldn't keep the speed buff after leaving the menu, even if the Chubby Chaser item was never swapped out.
2. Whenever I would spring an inflation trap, the red bar in the minigame wouldn't show up, making it impossible to tell whether or not I was losing. I even tried doing nothing in the minigame and the bar didnt show up. This also applied to the drinking game, but the parts in the drinking minigame where it says "Keep Going" and shows you the green bar would still show.
3. After beating the chocolate monster boss in the candy factory, I was able to speak to the head Gally in her office as if I had just beaten her regular boss fight. This would replay the cutscene where Gally #003 joins the party.
4. In the cave where you look for Vanessa, you're able to bounce over the doors that are covered in slime and get into the room where you have to fill a resevoir with water to be able to cross the gap with pool floaties (not the one where you can learn how to swim, the other one). I wasn't able to do anything in that room before actually getting the ability to shoot water, but I figured it was worth mentioning.
Now for the only major thing I found.
I was completely softlocked after unlocking the Bounce ability in the Seal of Wind. For some reason, I just was unable to bounce over the thorny bushes that blocked the path to the boss room, basically not letting me make any more progress in the Seal of Wind.
As for the new content, it all seems very well-made, as I wasn't really able to find anything groundbreaking in it. The new areas seem very lively and the new characters are adorable.
I might do a vore run in this version to see if there's anything funky that happens in there that I might've missed.
