Yay! Thanks for finishing the game!
SPOILERS:
The revelation was left ambiguous - the main character is surprised that the star is so bright in the sky (implying the star was super large and bright billions of years ago, since the main character is now on a planet billions of light years away), but the game doesn't really explain why that's important. We had more planned for the game, but ended up running into time constraints (typical game jam stuff haha).
