In order to get to the ending of the game, the player must encounter all of these events first, many of which are locked behind a specific set of parameters for each loop.

However, the player quickly discovers that regardless of the outcome of the investigation, time loops back to the initial discovery of the Gnosia infection.

The cast consists of 15 different characters, with the initial loop involving the player, Setsu, Raqio, SQ, and Gina.

Other characters join in future loops, including Stella, Comet, Chipie, Sha-Ming, Jonas, Kukrushka, Yuriko, Otome, Remnan, and Shigemichi.

Wanting to avoid putting anyone in cold sleep or having anyone die, they take advantage Manan's desire for immortality by tempting her with the Silver Key, which she could use to loop forever.

They give her access to a robot body known to be Kukrushka by the player and Setsu, and have her take the Silver Key through the portal into another universe.

Having broken free from their respective time loops, the player and Setsu finally take a moment to relax together without having to worry about the future.

Gnosia's development first began in 2015 by four-person indie studio Petit Depotto, being their second video game released after Unholy Heights.

It was eventually announced for a PlayStation Vita release in 2017, and was ultimately published by Mebius in Japan on June 20, 2019, shortly after the platform was discontinued.

The team received advice from Amphibian, the designer behind a similar game called Raging Loop, which helped the process along.

This logic was the same for why Unholy Heights released on the Xbox 360 despite being unpopular in Japan and late in its life, adding that having a small userbase typically leads to better reviews and the ability to target would-be fans more directly.

[15] Heidi Kemps of GameSpot offered both compliments and criticisms, lauding Gnosia's "intriguing story that slowly reveals its truths, keeping you interested in coming back for more," while lamenting the lack of character dialogue during discussions.

[14] Heather Johnson Yu of HeyPoorPlayer echoed Kemps' sentiments, both negative and positive, with a glowing addition that Gnosia was "my contender for GOTY 2021.

"[18] The limited dialogue options were a dealbreaker for Igor Rangel of Switch Brasil, who considered the immersion "shallow" and suggested voice acting to offset the response issues.
