Double Fine has yet to formally unveil their Kickstarter funded Double Fine Adventure, but they do appear to be ready to talk about Ron Gilbert's project with the studio.
The legendary adventure game studio sent Polygon a handful of puzzle pieces that when assembled appear to be an invite to a showing of "a new game by Ron Gilbert and Double Fine".
The project has been in the works for a while and hotly anticipated by fans as well. We're getting ever closer to E3 and if DF is sending out invites to some sort of event, it shouldn't be long at all now until we know what Gilbert is up to.
