Reminiscence in the Night (Platinum Longplay - Part 1: Love/A Fascinating Novel Endings)
In Reminiscence in the Night, you're a self-named character who wakes up on the living room floor with amnesia. You slowly learn about your existence by examining items around the room. It's a pretty straightforward adventure game with 4 possible endings. While there are many options, only a few of them really matter for getting the endings and trophies which I will explain below.
The game branches out in a couple different ways based on dialogue choices, but other than that is pretty linear. In this playthrough, we'll unlock "I Saw a Friend", "Guilt", "Friendship", "A Fascinating Novel", "Love" and "A Gift of Goodbye"
At 11:20, choose "Why Have You Waited For Me?" and this will put you on the path to getting all the teddy bear related trophies. Go upstairs after the conversation and examine the Teddy, but DON'T fix it. You'll need to do this for the "Guilt" trophy later. When you return to Sofia at 13:57, you will get the Trophy "A Gift of Goodbye" when you learn about why you have the teddy.
At 33:40, when talking to Sofia the next night, tell her about the man in the mirror to unlock "I Saw a Friend".
At 51:11, when you run into the man from the nightmare, talk about the Teddy, and if you didn't fix it, you will unlock "Guilt"
At 56:10, choose "I'm Sorry For Doubting You", and you will unlock "Friendship" and be on the path to unlock either the "Love" or "A Fascinating Novel" endings.
You can choose to stay at 1:00:45 to unlock "A Fascinating Novel", or choose not to stay to unlock "Love". Both endings are featured in this playthrough via save scrubbing.
