Slay the Spire video game

Slay the Spire is a premier roguelike deck-building video game originally released in 2019. It was developed by Mega Crit, an independent game studio based in Seattle, Washington. While the game was initially developed using the libGDX framework, its highly anticipated sequel, Slay the Spire II, transitioned to the Godot engine due to changes in industry licensing environments.

As a digital software product, its 'manufacturing' is centered in the United States where the code and assets were created, though it is distributed globally via digital storefronts like Steam, PlayStation Network, and the Nintendo eShop. The brand remains under the independent ownership of its original founding company, Mega Crit, which is led by founders Anthony Giovannetti and Casey Yano. While Humble Bundle handled publishing for console and mobile ports for the original title, the core intellectual property and ultimate control of the franchise rest with Mega Crit.
