Glad you liked it!
Also that's a fair point. I did think of another ending where they just choose one of their previous ideas but it didn't feel like it would fit, it would feel like it was just inserted for the sake of having multiple endings.
Its spin-off, The Puppeteer: Lamentation, is the closest thing to this, though :)
Also sure go ahead! You won't be the first and I sure hope you won't be the last XD
