Originally a niche videogame that found minor success only in Europe, the original Bridge Constructor exploded in popularity when a GIF of a barely-completed puzzle was posted to Reddit. Now a successful series with multiple spinoffs to its name, the most recent, Bridge Constructor Portal, launched on Switch on Wednesday. It follows the traditional Bridge Constructor game design—construct a bridge that will carry one or more vehicles between two points—but adds some Portal flair, including the quintessential portals, Propulsion and Repulsion Gels, lonely killer Sentry Turrets, Weighted Companion Cubes, and the trademark absurdist dark humor.
