I don't like reading, but this game almost convinced me that I do.
In fact, I don't think I've played a game that isn't a visual novel that involves a lot of reading and it's fun. I'm glad there is no time limit and it's just on you to put the pieces together.
Highlighted words do make the game much more comfortable, but for some it might be too patronizing. One suggestion which is more of an extra feature rather than a fix is difficulty levels, which change how difficult the text is to parse, maybe with more flavor text or no highlights.
