I recently showed this game to my brother after I played and finished it for the first time. He really seems interested in it, but he’s disabled. I got it worked out where he can use a console controller to play the game, but the game’s difficulty will really kill his experience.

Offering a simple choice of difficulty is a good first step in accessibilty, allowing some flexibility in the main challenge involved, such as level of AI, speed of enemies or difficulty of puzzles. This can be taken further by offering more detailed options for individual elements of game difficulty. Allow as wide a choice as possible, from very easy to hardcore.
