Galactic Puzzle Hunt 2020

Galactic Puzzle Hunt 2021, titled 20/20 Vision, was the fourth iteration of the Galactic Puzzle Hunt, run by ✈✈✈ Galactic Trendsetters ✈✈✈. Despite taking place in July-August 2021, the puzzle hunt was branded as "Galactic Puzzle Hunt 2020". The puzzle hunt featured five distinct rounds, with an intro round, and four main rounds themed around optical devices, with most of the rounds having unique mechanisms that affect the puzzles or the unlock structure. This hunt also saw the highest participation of any Galactic Puzzle Hunt so far, with 951 registered teams, and 623 teams having solved at least one puzzle. A total of 76 teams have solved the Telescope metapuzzle and thus finished the hunt.

Plot
Team members wake up in March 13, 2020. The Galactic Puzzle Hunt is going to start soon, but nobody can find their glasses. At this point, teams now start solving puzzles. Though the intro round puzzles are initially blurry, it takes the eyes one hour to adjust to each of them, at which point they become clearer. After solving the intro round, teams discover that they have left themselves clues for their glasses' whereabouts on four optical devices ("sights"), with each them being a round in itself:


 * Night Vision Goggles
 * Periscope
 * Microscope
 * Binoculars

Once teams solve the four metas of these rounds, the Four Sights meta opens, and solving that unlocks the final Telescope meta.

Structure
The hunt is divided into five main rounds. Most of the rounds have a signature mechanism that uniquely distinguishes them and affects the puzzles or unlock structure.
