I wanted the focus in this one to be the journey, not the destination - I wanted to explore feelings of lacking agency while still being able to react to events around you.
Still, I feel like a fourth ending would be interesting. Part of the journey IS the destination. Like, it could be a secret ending or something. Or just insanely difficult to get in general. I'm not saying to make it easy, just that there's no real way to win. Unless you're purposefully going for the willing departure ending (or the other 2) but also... this is a video game. There's usually a clearable objective in a game depending upon which path you choose. How difficult said path is depends on what it is.
