No, that’s not a screenshot from Fez, Polytron’s “not a PC game” that’s probably coming to PC soon. And while Melodisle‘s general approach to its genre – set players lose in a semi-open area and put them through a gauntlet of slow-burn, eureka moment puzzles – is similar, its main mechanic marches to the beat of its own drum. Or, well, not a drum per se, but some kind of synthesized midi vocal chirp sound. It’s musical, is what I’m saying. You sing at the game world, and things happen. It’s an interesting conceit that makes for some charming (though occasionally convoluted) puzzling. Thoughts after the break.
