I'm still taunted by this game, if I can even call it that. The best way to describe this is to call it an emotional experience. My friend said I should just watch the gameplay on youtube, and I completely forgot he said that, and downloaded the game anyway. No regrets. I gasped, cried, smiled, and screamed. When it ended, I felt a lump in my throat and an overwhelming sadness. At times, it felt like I was being forced to read someone's diary, and it made me feel very uncomfortable. 

One thing I loved about the gameplay, is that it made me wish games' development courses were taught like this. 

The beginner's guide is a collection of mini-games, or ideas for games that weren't completed. It's 'Coda's' journal entries. I wish I had better vocabulary to describe this experience, I wish it was a longer game, and I wish I knew if Coda was real or not.
