Iam giving the best rate. Even on Illiterate it is pretty hard game, but it has an idea and the reason to be so hard.
Sure, Spastic and Illiterate are not exatly disabilities, but still they are indeed handicaps (especially the spastic is a giant handicap for any kind of game)
And I thought before the crippled will be the hardest option, how even could it be posible to make it through all those platforms?!.. Oh I see now. Wow, that was unexpected.
I will respond on early reviews here about "more humility, portrays of ignorance" and such.
You are forgetting one main thing. the "crippled" is the same person as any of us. Anyone among us can get any kind of injury or handicap and got to DEAL with it somehow in its life. Deal with changes, emotions, new obstacles and judgements.
And that is the main point about this game I love. I had to deal with any problem I get to finnish the game.
