This is a super cool one-player game, but it's about exorcising trauma, and to do that it's first going to call it up. Consequently, this is *not* for everyone. If you've got stuff that it's safer not to confront, the mechanics of this game are good at drawing stuff out of you, so just don't play it.
If you *do* have stuff you don't mind confronting, still keep an eye on the safety mechanism at the end of the game, and hit stop if you need to.
I don't know that I'd recommend to play this, unless you're very confident it's not going to call up more than you want to deal with, but it's a heck of a design and worth checking out for that reason alone.
