A great work! And, an indeed playable game :) I guess generative AI should definitely improve currently existing procedural generation pipelines and build rich worlds while also requiring less effort to achieve that.
Indeed, I think generative AI will have a huge impact in games, and the biggest change for me will be NPC agents ( from the transformers library, not RL agents ) but it would have been way too complex and unstable to implement in 2 days.
