Earthlock

The game plays as a non-linear role-playing video game with turn based battles. In combat, characters fight in pairs - a "warrior" and a "protector". The warrior uses consumable items such as ammunition, while the protector can perform spells like healing and shields. When the characters are damaged by enemies, they accumulate support points, which can be used to activate other moves. Pairing different combinations of characters unlocks different moves and tactics, greatly affecting the flow of battle.

The game's story takes place in the world of Umbra, where a cataclysmic event occurs that stops the planet from spinning. This leaves part of the world scorched by constant sunlight, part of it perpetually cold due to lack of sunlight, and a patch of livable land in between. The incident ends up burying much of the past advanced civilization, but humanity survives and society begins anew in the habitable part of the planet. The story follows the adventurer Amon, who, among his usual activities of scavenging ruins, gets entangled in a much larger conflict with the ruling Suvian Empire.

The game is inspired by early Square Japanese role-playing games, though Snowcastle wanted to subvert common genre character stereotypes. Development for the game started as early as 2011, with a pre-alpha build trailer being released in May 2013. The game was originally just known by its subtitle, Festival of Magic.

In November 2013, the game was placed on crowdfunding platform Kickstarter with the aim of securing $250,000 in funding. However, Snowcastle later pulled from the platform, due to it getting lost in the crowd during the holiday season. A fresh Kickstarter campaign was launched in March 2014 with a lowered goal of $150,000. This second campaign was successful, raising $178,000 in April 2014. The game's plot was written by comic book writer Magnus Aspli.

Prior to its re-release, the game received an aggregate score of 56/100 for its PlayStation 4 version and 66/100 for its Xbox One version, indicating "mixed or average" reviews. Its post-revamp Nintendo Switch version received a higher, though still mixed score of 73/100.

The game received a more casual spin-off, Ikonei Island: An Earthlock Adventure, a single-player or co-op adventure and crafting game about exploring a mysterious island. It was initially released for PC on November 9, 2023, and, later, for PlayStation 4, PlayStation 5, Xbox One, and Xbox Series X/S, on March 21, 2024. A sequel, Earthlock 2, was also announced in 2020, and planned for release in 2022, although it was delayed several times. The sequel was re-revealed in 2024, with the plot revolving around exploring and bringing life back to the Desert of Kor using a special "Desert Ship". An additional game is reportedly planned due to a deal between Snowcastle Games and Jagex.
