The Mirror, an open-source effort to create an open Roblox or Fortnite alternative that we first covered in 2022 has just announced a massive change. They are no longer going to be building on top of the free and open-source Godot game engine. Details of the changes from the Mirror blog:Weve made the extremely difficult decision to transition The Mirror from Godot.First, Id like to give a massive thank you to everyone in the community for putting in so much time to create amazing software for free.
