The "?" icon in the upper open a small modal that says:

"This Is A Thing

This is an exploration of the idea that we can't control everything in our lives, but that we do have some agency in how we feel. This was inspired by writings from Seneca, Epictetus, and other Stoic thinkers. I hope you enjoy it!

If you have suggestions or notice any bugs, please feel free to contact the developer."

Just a thought ... move the "Click anywhere to begin" to initial text from above. Including that explanation upfront might make clicking to begin a little more comfortable.

I lasted 5 seconds. Oh, there was supposed to be sound?

Edit: tried again with sound turned up. Still silent but I guess I missed the point.

There is text on the bottom that is trying to say something. Can only see the top pixel of text in Android Firefox most of the time.

My left ear enjoyed this
