Game moving serious topics, serious problems that exist and will exist.
Things placed there are especially important for people who are awfully critical/hating/impatient toward people with disabilities, and instead of help that those people may desperately need... they send hate that can only further crush that person and push them to the point of suicide.
It's a really good game, showing the perspective of the person with those issues, and the mentality of some people that are met on the way, not understanding.. and instead of helping, they kick the laying down person further... and maybe help to do something - like cross a gap - but at what cost, while it didn't costed them nothing and yet they still just had to add their painful comment.
Also those comments of the people and on the signs, those can represent either people saying those things, or our own thoughts, self-loathing, pain, trauma, depression...
I really like 'depth' in the game, deep games, and it sure is one of them.
