Controllable has many exciting features such as: being able to change the binding of every button, allowing you to quick craft with one click from the recipe book, easy navigation of menus and inventory using the direcitonal pad, and the best support for other mods due to it's underlying codebase that developers can easily hook into! Controllable not only makes the game more accessible by enabling controller support, it allows multiple instances of the game to be played on the same computer something you can't do with a mouse and keyboard. There are many reasons why players find using a controller a better experience.
Unlike Bedrock Edition, the Java Edition of Minecraft does not allow players to use a controller to play the game.
