Hello, I come to you because I have seen many people complain about the game's catastrophic controller support. So I removed it by default. But you can still assign controller keys to the game: that's how.
By pressing esc in the game, you will be able to access the settings. Then, from the input menu, select your controller. You will just have to assign each buttons of your controller to the buttons starting with the ">" sign at the bottom of the list.
I hope you will enjoy the controller support in the game. I thank Hawk Zombie for his review of the game. Sorry for all the problems. I wish you a pleasant experience on The Last Duskreaper.
