This is truly excellent... once I got there.
So, when you purchase, you get a download for a PDF with a QR code to scan or a button to click. Scanning the QR code on mobile just took me back to the store page with the option to purchase. Only after reading the FAQ and learning that I needed an account to gain access did I partly figure it out.
Effectively, you need to be logged in with a HPLHS account prior to clicking on the link in the PDF. There's no prompt to login otherwise.
Another caveat was that, on Mac, the links in the PDF don't work in the Preview app. I had to download Acrobat Reader to actually get to the player.
I'm not sure the mobile experience, but I'd assume you'd need to be logged in as well. Clicking the links in the PDF did nothing there. They do mention an app in their FAQ called "Twist Tales", but I'm not a big fan of having to download an app I don't need otherwise.
A point on the audio: My use case is playing this on a Chrome-compatible browser on my Mac, but I wanted to Airplay to my better speakers. I have a Sonos Arc with surround speakers. On the rear speakers, I'd get constant glitches, so I killed those. Not sure how these tracks were recorded/output, but I'd get little split second voice and effects.
That said, HPLHS clearly put a ton of work into this, and I'll be trying to get through a lot of these. I'd highly recommend it for less than $18.
