Thimbleweed Park, Ron Gilbert’s charming 2017 adventure game, just got a surprise free spin-off. The new game, Delores: A Thimbleweed Park Mini-Adventure, is available to download now on Steam and the Epic Games Store. It weighs in at just 52MB.

The new game is a parallel story following Dolores, one of the main characters from the original game, getting a job as a photographer. It’s designed as a test for Gilbert’s new adventure game engine, which is why it’s free–don’t expect an experience as long as the original. It is not available on consoles.

Here’s the launch trailer for the new adventure, if you need further convincing to download a free game.

Thimbleweed Park is also discounted by 60% on Steam and the Epic Games Store right now, but that discount is due to end very soon.

The original game received a 7/10 in GameSpot’s 2017 review. Reviewer Matt Espineli described the game as “a time capsule that reminds us what we love about the point-and-click genre while still retaining many of its unremedied issues.”
