Nice work, I like the way the story starts, it has a very mundane description but then subtle cues like visiting a mineshaft give us the sense that it's not a normal day.
I think some of the passages are a bit long, we could get to the choices in the story a bit earlier. The choices also don't lead to different outcomes, so it might be good to have some different pathways. The final passage is blank, I would throw in a "to be continued..." if it's not done so it doesn't look like an error.
In the current setup, the content gets cut off by the bottom of the browser page on my screen. If you want to have long passages, you need to enable scroll bars. The only way I was able to click through the story by zooming out in the browser.
