I really enjoy choose your own adventure games, I liked the art and the sudden shift from black to white, it startled me when it first happened. If it had music and sound effects like wind, creaky door, rustling through bushes, etc. I like the idea and I hope you continue working on it since you and your partner put all this effort in.
Some Resources I Recommend
For sound effects I use Pixabay.
For music I use BeepBox or SoundTrap (The free version is a good starting point if you never made music before)
