I believe this game was honestly more of an experiment to see the challenges associated with making audio games. I see your point about the visuals but if you want an option to turn on visuals in the menu  then surely you would peek anyway. If you want an option to turn on visuals but can't trust yourself if you just turn off the monitor then GMT's point is not relevant. here is a link to a devlog the creator has made which you may find interesting:

In all seriousness now, I think the point of having visual elements is to make it acessible for not blind people too. Look it this way: If you have a blind friend, you could share this game with him and both YOU and HIM could experience the same game.

So you have a game in common you could talk about with said friend(even tho you both experienced them in diferent way). Imo that is pretty cool.

The visuals are a part of the game, if you want to experience it like a blind person would, it's completely up to you. If you lack the self-control, it is not the game's fault.
