Sorry, just checked and it's bugged out, which is really sad to us considering we spent the last couple of days implementing it and the only reason it's not in is one checkbox wasn't ticked on the last build, lol.
This game was made for a Game Jam so I'll ask if we can submit an updated build but we'll probably have to wait until it's over to reimplement it.
We'll temporarily remove that line of text from the features. Thanks a lot for letting us know of this so fast
Oh and [SPOILERS] to get the second ending, if it were working as it should have lol, you would need to reject Mr. Meat requests and don't look at the meat while cutting it. Do it enough times (5 times minimum out of 7) and when prompted to grab the knife in Day 3 you'll have the option to instead use it on Mr. Meat. We'll let people know once we are able to get it back up and running.
