They haven't open sourced the game itself yet. They made the announcement back in April on their own site.

Just fancy Markov chains with the ability to link bigger and bigger token sets. It can only ever kick off processing as a response and can never initiate any line of reasoning. This, along with the fact that its working set of data can never be updated moment-to-moment, means that it would be a physical impossibility for any LLM to achieve any real "reasoning" processes.
The backend is already open source (SpacetimeDB) but they announced that they will also be open sourcing the game code as well. But yes, the art assets will not be open but that's pretty standard for a lot of commercial games that later get open sourced (the open sourced id software projects for example).
