(Just had to log in to leave a review) Well, as a political/philosophical/metaphorical (what have you) piece of art this game is great. It's has a moving message gets to the point quickly and communicates that point quite eloquently through both story and the frustration induced by the game play itself (I started with crippled). It is also frank enough as to not go over most users heads.
From a game perspective it actually was quite fun to play. For the most part it was challenging and frustrating but not frustrating enough that my frustration outweighed my engagement in the game and wanting to see the rest of the content... for the most part. I'm aware others have already stated this but parts of this game (as a game) are in fact broken. I do understand that the frustration induced by the difficulty of the game play is part of the point you're trying to get across but your message will do no good if people get to fed up with the game to bother seeing it through. I think it might, as the very least, be helpful to have players start as the cripple by default. For me that was the part that got me hooked invested enough in the game to keep playing even when it became more frustrating due to the game mechanics. I really doubt I would have continued playing had I started with blindness or spastic because I wouldn't been to frustrated and distracted by the game play to actually see the statement you were trying to me.
Overall despite the game play flaws that in my opinion could use some ironing out I think this is a really unique gem of a game.
P.S. I am also aware this game was made under a time limit but that's no reason not to keep working on it. With some gameplay improvements I think this game could score quite a large audience.
Best of luck and merry Christmas,
just some guy.
