Again not much for my friends at itch.io I'm afraid. Unless you have a way to map your controller to keyboard keys and your controller thumbstick to the mouse. If that's the case then this update adds a lot more support for controller or keyboard. For more details see:

This patches also fixes a bug that made it very hard to progress in the storyline involving "Heimgzung".
