That’s “The Deepening”. It’s an interactive video thing with presentation like a game, so you modern people feel comfortable with it. You can’t (or at least we can’t) embed the thing, so here’s a link to it and a still image.

“Hey there UK Resistance. I thought you may be interested in Atom.com’s new game, The Deepening. It’s an 8-bit-inspired, playable web comedy short video – think those old “select your own adventure” books, but as a totally interactive video game with multiple endings and paths that the user can control” – Atom.com person.
