To me, as a sighted player, I had some trouble with the tutorial, starting with the text to speech not reading some words but spelling their letters out and continuting with the amount of information to take in without being able to pause or navigate (or listen again to specific lines of instruction). Unfortunately, and with it being a more abstract game, I think this was enough to make the experience difficult enough to not feel the abiity to push through. I think fine-tuning on this would be a good addition.
Perhaps for gamers who are better at parsing a lot of audio input this would not be a problem. For me, it was. :(
