You can toggle through hud types by clicking the little symbol. One of them is a very minimal option which doesn’t obscure the book. Just look on the bookshelf in the bottom left, you should be able to see the book marked “Death” in faded lettering.

Triggering either “Celestia cums” or “Celestia squirts” during pull-out will either fill the bottle with cum or urine respectively. If Twilight is not wearing a ball-gag, she’ll get the bottle afterwards.

You can trigger both by getting Celestia to pull out, then clicking on her butthole a number of times. She’ll fart the first few times but then a golden bowl will appear. Click the asshole again to trigger scat, click the cock to trigger watersports.
There’s also a hidden “Death” rune in the bottom left corner of the background that is obscured by the hud. Hiding the hud and clicking on it enables a few of the more fetishy combos.
I find it’s not working for me. There’s no buttons, and all I can do is click their faces to change them, and clicking celestia’s anus makes it twitch.

It literally says “Original sketch by Hoihoi” at the first screen. The following warning page even includes a warning for a “grotesque artstyle”. I’m not sure if I expected anything different than exactly what I got, but to answer your question, it is Hoihoi.
