I played this because it's one of the earliest visual novels and it's said to have inspired the Zero Escape games. At it's base it's a murder mystery in a ski lodge, but then it opens up to a bunch of genre shifting divergences in the flow chart. Based on early choices you can end up pivoting into a spy story, a purgatory loop, creepy pasta. It's very pulpy stuff but it's fun seeing how the pieces get reshuffled from one branch to another. And amazing to see how well realised the idea of a branching narrative was so early.
I'd love more games that do such significant tone shifts. I know that some route based games that turn up certain sliders but still ultimately fit in the same genre like Fate Stay Night. But I'd love to play more games that just totally diverge into wildly different ideas.
