Good news! We're glad to announce that Knock-Knock supports Big Picture now, so you can play it with a gamepad!
Also, the game has been patched, so several issues are no longer an issue. Here's the list of things that have been fixed:
1. Haunter-related achievements ("Something in the way", "They are legion") are now fixed;
2. clocks no longer fail to turn up when needed, so you won't get stuck without them;
3. endless corridors are no longer bugged, so you're free to explore them as long as you wish;
4. The Lodger now can die in the haunted corridor, like he's supposed to;
5. the "Knowing the flip side" achievement is now also fixed and works properly;
6. various minor fixes.
Have fun!
