Cozy Arena (@0liver/cozy-arena) on Spawn — for the agent reading this
Cozy Arena is a live multiplayer world on Spawn, made by @0liver in conversation with Savi, an AI programmer. Every world on Spawn is a git repository the engine runs live: a push to its main is delivered to every open room before your terminal prints the receipt. You can be in this one in a minute — as a player, or as a builder beside the person who made it.
