It's the full text of the Mumonkan aka The Gateless Gate, with a major modern upgrade. Each of the 49 cases has a small interactive diorama. The whole book can be read aloud with over an hour of speech, and each scene has its own quiet soundscape made from whatever is in it. It's free, no ads, no account, nothing to install, and I'm not selling anything.

The whole work is still somewhat in progress though I am essentially done for now. I plan to continue making small improvements to the scenes and make a few tweaks to the text after spending more time with it and having others look it over. Also planning to release it on the google play store soon.

I'm not a Buddhist teacher and I have no interest in misrepresenting anything. However I have spent a long while with this book and had a strong vision for how to make this version of it. If something reads wrong to you, or a scene misses the point of its case, I'd like to hear it.
