I enjoy it !!!!!

This game is really amazing, Its super intersting because it have a lot of surprises and with a lot of suspense.

BoR first play through

Just finished my first play through of Book of Regrets and really enjoyed it. I used to be a huge fan of "choose your own adventure" books growing up and this was one brought to life. BoR is a mysterious world full of quirky characters and tons of secrets that makes multiple play throughs seem worth it.

Needs some work

Kindred gamer

I love the story arc and the gameplay isn't bad either. But my phone threatens to crash every time I come across the demon in the attic and freezes up!
