The feedback hasn't really been to make the game harder but we have seen some people enjoy the game instead of simply struggling with it and thought that needs to be fixed. There is now a Nightmare difficulty in the game which unlocks after you've beaten any game mode in the Hard difficulty.
This is completely free update which is now included in the base game. Simply update the game to access this new difficulty.

How is Nightmare harder?
For Typing game mode you are now only allowed six mistakes before needing to start the floor again. The texts are also quite hard to type since there seems to be some brain fog going on.

For other game modes the biggest change is the moving platforms.
