Thaumistry is exactly what you want if you’re an Infocom fanboy like me. It has that thoughtful, funny writing Infocom spoiled us with, dozens of just-hard-enough puzzles, a cast of characters with enough personality to be interesting, an over-the-top set-piece climax, and all the refinements you expect from a modern adventure game. You can’t break it and make it unwinnable. You can’t die, with one obvious exception, blatantly telegraphed several turns before it happens. But this isn’t posturing, hipstery “art house” interactive fiction — it’s a hardcore, puzzles-first design. The heart of a 1980s text adventure throbs beneath all the 21st-century niceties.
