How is it possible that such a popular game has such lazy developers? So many years have passed, and the game still doesn't have a way to play with a controller. Using the keyboard is horrible in this kind of game, and from what I've read, some bosses are horribly designed.

And no, I don't want to use an external tool to map button after button on the controller. Is this a game abandoned by the developers?

Edit: Seeing how the devs haven't done anything to add controller support even though many have been asking for months for an update that would allow playing with a controller, I'm glad I got this game via a steam key for less than a dollar. This overrated game was made by lazy devs.
