Thank you!
We went for the "shocking" emotional ending to tell a story about about a kid that did bad things in his past and regrets it. So, the game starts in a flashback, he was remembering his grandad scolding him, that's why it is black and white. In the transition to the next scene and the following one, you can hear a heartbeat and a cardiac monitor. In reality, the kid was in a coma all this time, dreaming about his past regrets and fighting them. Then, on the transition to the last scene you no longer hear the heartbeat, only a flatline from the cardiac monitor... Then, well I don't think I need to explain what happens on the ending scene. 😅
