“So many games left to be designed.”

That’s designer Ron Gilbert’s plan for the future, but it won’t be happening at Double Fine Productions. The longtime Tim Schafer collaborator is moving on from Schafer’s studio, weeks after the launch of The Cave, which he worked on with Double Fine the past two years.

“I want to thank all the amazing people at Double Fine for all their hard work on The Cave,” said Gilbert on his blog. “It was a true pleasure to work with every one of them over the past two years. So much fun. I will miss them all. And of course to Tim for creating the opportunity to come there and make The Cave.”

Nobody involved has elaborated much on Gilbert’s reasoning for leaving (conspiracy!), but Schafer waved goodbye on Twitter.

“Sad to say @grumpygamer feels like it's time to spread his grumpy wings and fly,” said Shafer. “Good luck, Ron! Thanks for The Cave!”

In the coming weeks, Gilbert plans to post behind-the-scenes pictures and other details on his blog.
