OMG! Thank you so much for playing it again, and I’m so happy you enjoyed the second ending too! (^▽^)
I totally understand the third ending can be tricky—it’s a bit of a hidden secret! When you get to the last choice (whether or not to use the stake), stay on that screen without clicking anything for about 4 minutes and 33 seconds. I was inspired by John Cage’s 4'33"—though, truth be told, it's a few extra seconds longer. You can step away for a while until the music stops.
Some of my friends said it was too hard to figure out, so I really appreciate that you're determined to get all three endings! ♡ Feel free to reach out if you have any issues, and thanks again for all your support!
