‘Free-lude’ – a terrible term never to be used again in reference to a prelude given away for free. Sigils of Elohim is just such a thing, being a puzzle game that you can download and play right now without spending a penny. The video below does a good job of explaining the format of the puzzles, which seem easy enough but will undoubtedly cause me to pummel my keyboard with my fists as they become increasingly complex. I’ve got about as much spatial awareness as this chap. Success with the sigils will “unlock helpful items and relics within The Talos Principle“, which is the philosophical first-person puzzler due from Croteam later this year. Crap at puzzles I may be, but I’ll be playing for the writing of Tom Jubert and Jonas Kyratzes, and hoping to blunder through.
