In version 0.4.0, the main change is that the unused "Settings" button on the title screen has been replaced with an "Extras" button linking to a scene populated with a gallery for users to explore the game's assets and the credits menu. Users are also now able to go back to the title screen after winning the game, while the intentional "infinite" ending still exists.
