Deeper than you think
I can see where many people would quit this game, with all its confusing monologue at some points, as well as how it comes across with seemingly random concepts in the rooms, but the emotion and understanding that you actually get from the ending is extremely interesting and compelling.
I actually enjoyed this game a lot once I finished it, despite how it made me feel sad because of how this game could be applied in reality, and how I applied it in my own life. Great game.
