This is, as far as I can tell, the only entry in the Petite Mort division of the Spanish-language Ectocomp, all others being in the Grand Guignol division.
This is also the most educational game of the competition. It's essentially a guided tour of gruesome Madrid history, from torture devices to famous murders.
I learned a lot. The main interactivity is choosing which area to explore next. There is custom styling which was slightly hard to read (for best practices it's easier to read white text on dark grey than on black backgrounds) but had interesting images and even an embedded google maps link.
Overall, fun to learn from.
