Between Worlds

This book is about a 24 year old man who died, he doesn't know any details about his death, when we wakes up he appears in a white space with only a table and 3 chairs. He gets 3 choices, Go to get judged and go to heaven or hell, live another life where controls everything because it is actually a simulation, and where he can do both but doesn't get a choice the second time he dies. Because of the God making a mistake all three ends up in the same dimension needing to save the fabric of reality before Armageddon happens (and kill God of course)
