The tiny world of Polyarc’s mouse-based virtual reality game is getting bigger. Moss’ Twilight Garden expansion adds a new chapter to Quill’s adventure, with more puzzles and enemies to defeat and equipment to earn. The free update launches with the Oculus Quest on May 21 and comes to other VR platforms in June.

Mouse VR game Moss (a genre we never knew we needed but have lived too long without) will be out February 27 for PSVR. Here’s an adorable trailer.

No, this isn’t a Redwall tie-in, but nobody is going to stop you from pretending. This is Moss, an adventure game coming to PlayStation VR.
