Responding to a twitter query about extra levels or even a level editor, the Hotline Miami account today tweeted that "more will come." Some fans of the twitchy bludgeoning and blasting have already finished the game and are keen for more, more, more. More blood. More guns. More baseball bats. Just one more level. Just one more fragile little skull to cave in. Is that really so much to ask for? I can stop any time.
The same Twitter account also said that a forthcoming patch should address issues with both GOG and Steam version of the game, such as Steam achievements that don't update correctly, and that support for Xbox 360 gamepads is on the way. That's indie developers for you: quick on the draw.
